The Rocky Horror Show, with book, music, and lyrics by O'Brien, is "a musical that inspired the 1975 classic cult film, 'The Rocky Horror Picture Show,'" according to press notes. "It follows innocent couple Brad and Janet as they seek shelter at a mysterious old castle on a dark and stormy night, where they encounter transvestite Dr. Frank N Furter, his 'perfect' creation Rocky, and an assortment of other crazy creatures."
