In Jesus Christ Superstar Live in Concert, Legend takes on the title role, Jesus Christ, and Bareilles is Mary Magdalene, with a cast that also includes Brandon Victor Dixon as Judas, Alice Cooper as King Herod, Norm Lewis as Caiaphas, Ben Daniels as Pontius Pilate, Jason Tam as Peter, Jin Ha as Annas and Erik Gronwall as Simon Zealotes.

Both Legend and Bareilles said they were fans of the Jesus Christ Superstar music—and musical theater—while growing up.

"I was never the lead before, or never so prominently featured as I am in this show, so it's pretty exciting," Legend confessed about his musical past.
