In the second act of the magnificent musical parody Urinetown, the character of Bobby Strong - a novice revolutionary, and the show's ostensible leading man - sings "Run, Freedom, Run," a rousing call-to-arms to his fellow oppressed. The number, a sort of "Sit Down, You're Rockin' the Boat" from Guys & Dolls as seen through a Les Miserables filter, is one of those guaranteed show-stoppers designed to leave audiences cheering. At the Timber Lake Playhouse's Saturday-night performance of the show, however, this production number led to something even more thrilling.
