Starting out as a comedy writer for the Late Show with David Letterman, Steve Young had few interests outside of his day job. But while gathering material for a segment on the show, Steve stumbled onto a few vintage record albums that would change his life forever. Bizarre cast recordings -- marked "internal use only" -- revealed full-throated Broadway-style musical shows about some of the most recognizable corporations in America: General Electric, McDonald's, Ford, DuPont, Xerox. Steve didn't know much about musical theater, but these recordings delighted him in a way that nothing ever had. While tracking down rare albums, unseen footage, composers and performers, Steve forms unlikely friendships and discovers that this discarded musical genre starring tractors and bathtubs was bigger than Broadway.
