Get Goosebumps Watching Kelly Clarkson & Josh Groban Sing Phantom of The Opera Song

Josh Groban brought Kelly Clarkson out as a surprise guest for his PBS performance. They sing a goosebump-inducing cover of Phantom of the Opera‘s “All I Ask of You.”

“She’s one of the most versatile singers that I’ve ever heard,” Groban said introducing Clarkson. “She’s got the most beautiful voice that I’ve wanted to sing with for ages.”

For Groban’s Stages Broadway musicals cover album, Clarkson covers this beautiful duet together.
