Kate Hudson and Hugh Jackman are no strangers to performing onstage.

Hudson and Jackman play the real-life couple Claire and Mike Sardina, who were part of the Milwaukee-based Neil Diamond tribute act Lightning & Thunder, in the film Song Sung Blue.

The movie, which premiered on Christmas Day, is based on the 2008 documentary by the same name that follows the band’s early days and Claire and Mike’s relationship.

Ahead of the official theatrical release, Hudson and Jackman praised each other’s work and their experience on set. During a joint interview with PEOPLE at the 2025 Gotham Awards, Hudson complimented her costar, sharing, “His superpower is to connect, whether it’s onstage, whether it’s on set, whether it’s with anyone and everyone.”

Jackman also said that working alongside Hudson made him “a better actor” and mentioned her having the ability to be “prepared” while also “instinctive” with her work. The combination proved to be essential for them both as they took on the roles, parts that were different from what the actors had done in the past.

So, are Kate Hudson and Hugh Jackman really singing in Song Sung Blue? Here’s everything to know about their performances, including their past musical experiences.

Are Kate Hudson and Hugh Jackman singing in Song Sung Blue? 

Yes, it’s really Hudson and Jackman singing in the biographical musical drama.

“We recorded everything, and we sang everything live,” he said on The Howard Stern Show in December 2025. “I’ve done two musicals. Les Misérables, which we sang everything live, and The Greatest Showman, where everything was recorded. So this was like a hybrid.”

That same month, when asked on The Kelly Clarkson Show about what it was like to perform together, Hudson said, “It was the best.”

A behind-the-scenes look shared exclusively with PEOPLE a week before the movie’s premiere captured Hudson and Jackman as they recorded Diamond’s tune “Cherry, Cherry” in the studio, spliced between clips from the actual film.

Scott Bomar, who wrote the score and served as the movie’s executive producer on the soundtrack, told PEOPLE that it was the first song adapted for the project.

“I immediately heard Kate sing the background vocal part from Neil’s original version,” he said. “This is the only song on the soundtrack, which we added some additional instruments to for the soundtrack version.”

Did Hugh Jackman and Kate Hudson know each other before Song Sung Blue? 

Despite their on-screen chemistry as Claire and Mike, Hudson and Jackman didn’t know each other before Song Sung Blue.

While appearing on CBS Sunday Morning in December 2025, Jackman revealed that they only had briefly crossed paths. He explained, “It’s become a bit of a joke because I remember when we first met, but she has no recollection.”

“I don’t remember meeting him, which is so weird, because it was in my mom’s house,” Hudson said.

Though they weren’t familiar with each other before the movie, Jackman was instrumental in getting Hudson on board the film.

During the interview, the actor confessed that after seeing Hudson performing on CBS Sunday Morning, he immediately texted writer and director Craig Brewer to try to get her attached to the project.

“I turn it on, and there was Kate promoting her debut solo album,” Jackman recalled. “I texted Craig Brewer, the writer-director, and I said, ‘Kate Hudson is Claire, Claire is Kate.’ And he just said, ‘Oh my god, perfect.’ “

Jackman also took the opportunity to praise Hudson’s performance in the movie, sharing, “As much as I could see it and feel it, nothing prepared me from day one of rehearsal through ’til the end, until I saw the movie, of Kate’s performance.”

“I could feel it. You just know, I’m like, ‘She’s going to be perfect, she’s amazing, and I love her, and I love her as an actress,’ “ he continued. “But then when there’s somehow an alchemy of a part to an actress, at that time, when that all comes together … magic.”
