For more than three decades, it was common for American companies to put on “industrial musicals” for their employees. These elaborate productions could rival Broadway shows, and featured original songs about the company and its products.

This is a story about bathroom remodeling, corporate art, and one man’s obsession with a forgotten corner of pop culture. Featuring comedy writer and collector Steve Young.
