The Drowsy Chaperone won five 2006 Tony Awards, including Best Book (Bob Martin and Don McKellar) and Best Score of a Musical (Lisa Lambert and Greg Morrison), and seven Drama Desk Awards, including Best Musical. Directed by Casey Nicholaw, the show also stars Mari Davi, Jo Anne Worley, Danny Burstein, Peter Bartlett, and Beth Leavel.
