Years ago, Steve Young, a writer for Late Night with David Letterman, ignited a personal obsession when he discovered recordings from the strange and hilarious world of industrial musicals: full-throated, Broadway-style musical shows that were only intended for employees of the most recognizable corporations in America. Ubiquitous from the 1950s into the 80s, these “secret” shows featured writers and performers who would become legends, such as Chita Rivera, Kander & Ebb, Florence Henderson and Bob Fosse. Unearthing rare albums and unseen footage from such hits as The Bathrooms Are Coming!, this eccentric journey down Memory Lane might redefine your favorite showtunes. With David Letterman, Martin Short, Chita Rivera, Susan Stroman, Jello Biafra, Florence Henderson. (US 2018) Director: Dava Whisenant.
