14 major changes 'Daisy Jones and The Six' made from the bestselling book

"Daisy Jones & The Six" was released alongside an original soundtrack titled "Aurora," produced by Blake Mills and recorded by the cast at Sound City Studios in Los Angeles.

The title is one of the few details that it shares with the album described in the book.

Daisy Jones & The Six, the fictional band at the center of the story, records an award-winning and critically acclaimed album called "Aurora." Reid's novel describes a 10-song tracklist and includes an official lyric booklet.

In the show, only three songs retain their original names: the title track, "Please," and "Regret Me."

In addition to his role as producer, Mills was tasked with rewriting the real-life versions of the songs. He also enlisted some famous cowriters like Phoebe Bridgers and Marcus Mumford.

Indeed, when Daisy's angry-woman anthem "Regret Me" was released as a single before the show premiered, fans immediately noticed that nearly all the lyrics had been changed, including some iconic lines.

In the book, The Six's drummer Warren declares: "You know when she had me? When I knew that song was fucking great? When she said, 'When you think of me, I hope it ruins rock 'n' roll.'"

That line was cut from the show's final version of the song, among many others.

In the show, Daisy's birth name is revealed as Margaret.

She changes it to Daisy when she hits the Los Angeles music scene, symbolizing her desire to forget her neglectful childhood.

In the book, Pittsburgh-born siblings Billy and Graham Dunne start a blues-rock band together.

They call themselves The Dunne Brothers and go on to recruit local musicians: Warren (drummer), Pete (bassist), and Chuck (rhythm guitarist).

After Chuck is drafted for the Vietnam War, the band asks Pete's brother Eddie to take his place.

Later, after Karen joins the group as a keyboardist, they rename themselves The Six because there are six bandmates. (Graham and Warren also say they liked how it sounded like "The Sex.")

Conversely, in the show, Graham starts the band with his schoolmates and they quietly trick Billy into becoming their frontman.

"I never agreed to be in their band," Billy tells the camera. "I said that I would listen, maybe give 'em some pointers."

Additionally, there are only five bandmates in the show. When Karen suggests the new name, she includes Billy's girlfriend Camila in her calculation.

In the book, Eddie is not an original member of The Six. Rather, his brother Pete is the band's bassist.

In the show, Pete doesn't exist. Instead, Eddie is a combination of the two — he switches from rhythm guitar to bass — and his last name is Roundtree instead of Loving.

In the book, Chuck dies at war in Cambodia.

The loss helps contextualize Billy's dismissive attitude towards Eddie, who takes Chuck's place in the band.

"Nobody could be Chuck," Billy says in the book. "But then we kept getting more shows and I didn't want to keep playing rhythm guitar onstage. So we invited Eddie. Figured he could pitch in for a little while."

In the book, Warren's last name is Rhodes and there's no indication that he's a Latino man. But when Sebastian Chacon was cast, he had a conversation with the showrunners about changing Warren's last name to maintain some of his own heritage.

"I did a lot of research trying to see if there was a white, American band that had a Latin anything. And they don't," Chacon told Insider. "So I wanted that to be a part of it somehow and I didn't wanna necessarily erase this special thing."

Chacon said he "threw out a bunch of last names" and Rojas is the one that stuck.

In the book, Simone's sexuality is unknown. Her scenes focus largely on her friendship with Daisy and her disco career in New York, but we know that she eventually gets married and has a daughter named Trina.

But in the show, Simone's queerness is made explicit in the third episode when she meets her love interest, a DJ named Bernie.

"I think it was a great addition because gay people created disco music," Be told Insider. "It was part of the movement, it was part of why the music was so relevant. So making Simone a queer character and having her be the pioneer, the face, and one of the fundamental aspects of this genre coming to life, I thought was super important."

The novel's version of Karen is a tomboy. She actively rejects feminine fashion because she wants to be seen as a musician more than a woman.

"I felt like I couldn't focus on playing if I dressed in miniskirts and boots and all that. I mean, I liked that look, but I wore high-waisted jeans and turtlenecks most of the time," she says.

This stands in contrast to Daisy, who tends to wear revealing clothing regardless of sexist reactions.

"When I auditioned for the Winters, I had this really great minidress I'd just bought, it was pale blue with a big belt across it. It felt like a lucky dress," Karen explains. "Well, the day I tried out, I didn't wear it. Because I knew they'd see a girl. And I wanted them to see a keyboardist. So I wore jeans and a University of Chicago T-shirt I stole from my brother."

She adds: "Daisy wasn't like that. It would have never occurred to Daisy to do that."

Conversely, in the show, Karen is styled in many of the same '70s silhouettes and flowy fabrics as Daisy. She even wears deep V-necks throughout the show, despite a scene where she explicitly tells their tour manager that she won't.

"Rod told me to wear low-cut shirts and I said, 'Dream on,'" she says in the book. "And that was about the end of that."

In the book, Billy meets Camila at a hotel where The Six (then called The Dunne Brothers) were booked as a wedding band.

"I was standing there in the hotel lobby, on my way to the van. And she was waiting on a customer over at the bar," he says. "You could tell, just watching her, that she wasn't taking shit from anybody."

In the show, they meet at a laundromat instead, although their flirty conversation retains Billy's original pickup line: "If you give me your number I'll write a song about you."

Indeed, Billy writes many songs about Camila, including a single called "Señora," which isn't mentioned in the show. They fall in love while the band is building their reputation and taking gigs in other cities, even though they weren't finding much success yet.

"She'd say, 'If I wanted to be with a rich guy, I wouldn't have given my number to the singer of a wedding band,'" Billy recalls.

When Billy decides to move the band from Pittsburgh to LA, Camila dumps him.

"She said, 'You want me to just follow you around?' I said, 'I guess,'" Billy recalls in the book. "She took a moment and then she said, 'No, thank you.'"

Camila adds: "I was sick to my stomach without him. I was... kicking myself. Every day. Waking up in tears. My mom kept telling me to track him down. To take it back. But it felt like it was too late. He'd gone on without me. To make his dreams come true. As he should have."

Later, after The Six inks a deal with Runner Records, Billy calls Camila and proposes: "If I had a record contract, would you marry me?" She only moves to LA after that phone call and they're already engaged by the time she gets pregnant.

In the show, however, Camila decides to join Billy's journey before the band leaves Pittsburgh. Their proposal scene was cut and they don't even discuss getting married before their shotgun wedding in episode two.

In the book, the famed producer Teddy Price comes to see The Six perform at the Troubador in LA.

Billy recalls: "First thing Teddy says is — and you have to remember he had this real thick upper-crust British accent — 'You've got a hell of a talent for writing about that girl.'"

In the show, Billy runs into Teddy at a grocery store, already knowing who Teddy is, and begs him to give The Six a chance.

Additionally, the show's version of Teddy is American, not British — and certainly isn't, as Warren describes him in the book, "ugly as sin."

Actor Tom Wright told Insider that he "attempted to channel" real-life producers and music executives like Quincy Jones, Berry Gordy, and Al Bell.

The novel's version of Camila is headstrong and decisive, described by Karen as "a force to be reckoned with."

This is underscored when she gives birth to her first child without the support of her husband, who is deep into his addiction at this point in the story.

Although Teddy drives him to the hospital, Billy can't bear to meet his daughter while intoxicated.

"Right then, giving up on Billy felt easier than trying to have faith. I wanted to say, 'Tell him I'll raise this baby on my own,'" Camila says in the book. "But I had to keep trying for what I wanted for me and my kid. So I told Teddy, 'Tell him he can start to be a father this second or he's going to rehab. Now.'"

Instead, the show depicts Camila in the hospital as lonely and brokenhearted. Teddy takes Billy to rehab without consulting her.

A good chunk of episode three follows The Six's efforts to find a new frontman after Billy leaves rehab. Eddie even attempts to step into the role.

By contrast, in the book, Billy never entertains quitting the band, immediately resolving to balance his sobriety and his family with his career.

He also promises to stay faithful to Camila when he returns home and finally meets their daughter.

"I couldn't believe what I put Camila through and I couldn't believe that she was still standing there, giving me another shot. I didn't deserve it. And I knew it," Billy says in the book. "I told her then that I would spend the rest of our life together trying to be as good as she deserved."

Camila adds: "I think you have to have faith in people before they earn it. Otherwise it's not faith, right?"

In addition to Julia, the couple's first child, Billy and Camila also welcome twin girls in the book named Susana and Maria.

Camila is pregnant with the twins while The Six is touring to support their second album, "SevenEightNine." When the tour is over, Billy returns home to be with his family.

"I went on this long epic speech to Camila, I said, 'I'm giving it all up, honey. I don't want anything but this family. The five of us. That's all. I want or need,'" Billy says in the book.

He continues: "And Camila — keep in mind she's just had a C-section — I will never forget it, she goes, 'Oh shut the hell up, Billy. I married a musician. You'll be a musician. If I wanted to drive a station wagon and have a meatloaf ready at six o'clock, I would have married my father.'"
