Exclusive First Listen: Sierra Boggess' Big Number From Andrew Lloyd Webber's School of Rock

Class will begin for Sierra Boggess on November 9 when she starts performances in Andrew Lloyd Webber's School of Rock—The Musical and we have an exclusive first listen of her big second act number! The three-time Broadway.com Choice Award winner and Olivier nominee is a long-time collaborator of the legendary composer, who has penned her another epic tune (of course he did): " Where Did The Rock Go." Check it out, with lyrics by Glenn Slater, below and then the show, which will officially stick it to the man open on December 6 at the Main Stem's Winter Garden Theatre.
