Based on the hit 2003 film of the same, School of Rock features music from the movie, as well as an original score by Lloyd Webber, lyrics by Glenn Slater, a book by Julian Fellowes and direction by Laurence Connor.

The musical, according to press notes, “follows Dewey Finn, a failed, wannabe rock star who decides to earn a few extra bucks by posing as a substitute teacher at a prestigious prep school. There he turns a class of straight-A students into a guitar-shredding, bass-slapping, mind-blowing rock band. While teaching these pint-sized prodigies what it means to truly rock, Dewey falls for the school’s beautiful, but uptight headmistress, helping her rediscover the wild child within.”
