School of Rock — The Musical is based on the 2003 Richard Linklater film featuring Jack Black as a failing rocker who forms a band with his talented students in hopes of winning the Battle of the Bands. Alex Brightman stars in the new musical. He and the cast of precocious kids took the stage at the Gramercy Theatre to rock out with the Glenn Slater (new lyrics) and Andrew Lloyd Webber (new music) tunes "You're In the Band," and "Stick It to the Man" as well as "Teacher's Pet," the lone holdout from the film.
