Following a stage success, a cult film and the subject of many revivals since its birth in 1973, this is the history of "Rocky Horror" in all its forms, tracing its rise form a fringe production in Chelsea to one of 20th Century Fox's most prized and reliable "earners". James Harding is the author of 15 books. He broadcasts frequently on "Kaleidoscope" and contributes books and record reviews to "Punch", "The Listener" and "Literary Review".
