The iconic lips that open The Rocky Horror Picture Show are Patricia's- however it is Richard O'Brien who sings the song 'Science Fiction, Double Feature'.
Her nephew, Johnny Quinn, is the drummer for band Snow Patrol.
Patricia Quinn: Can I explain the success of Rocky? ... Sex, drugs and rock 'n' roll. That would seem to be it.
Patricia Quinn: I've never been able to understand why all of the Magentas I've seen at later productions of the show were so plump. And why do they all identify with me? The reply from everyone was that they couldn't afford Columbia's sequins! They could afford the maid's frock.
Patricia Quinn: People don't realise that, even though Rocky was only an hour and twenty minutes, you really had to get out there and work. It's like going to a party every night. You can't do it half-arsed. It's not like a Noel Coward comedy, sitting with teacups in a drawing room. It was physically quite grueling.
