The soundtrack for the upcoming biopic Judy will feature two duets with titular star Renée Zellweger—one with Sam Smith and another with Rufus Wainwright.

Grammy and Oscar winner Smith will sing “Get Happy” alongside Zellweger while Wainwright, a Grammy nominee for his album Rufus Does Judy at Carnegie Hall, will duet on “Have Yourself a Merry Little Christmas.”

The soundtrack will be released September 27 to coincide with the film’s wide release on the same day. Songs from the film will also be on the album, including “For Once in My Life,” “Come Rain or Come Shine,” and “Over the Rainbow.”

“[Garland] has remained as one of the icons of my life,” said the openly gay Smith. “She was one of the bravest humans out there and her vulnerability and honesty in her art still gives me goose bumps like it did the first time. It was truly an honor to sing with Renée. Nobody could have played Judy as well as her.”

Starring opposite Zellweger is Finn Wittrock as Garland's fifth husband, Mickey Deans.
