The answer is The Rocky Horror Picture Show, and the role was the one that made a superstar out of Tim Curry - Dr. Frank N. Furter. Tim himself has had almost the exact opposite of Mick's career - success as an actor but only mild singing success - he released three LP's in the latter part of the 70s and early 80s, and had two minor hits, Paradise Garage and I Do The Rock. Purely out of prurient interest, let's see what they sounded like, shall we?
So... next question!
In The rocky Horror Picture Show, who portrays Eddie, an ex-delivery boy?
