Photographer Steve Emberton on shooting this famous photo of Sid and Nacy: "We knocked on the door but nobody answered. I knocked a bit louder and still nobody answered and I was beginning to wonder if it was going to happen at all, and I knocked really loud and eventually the door opened and it was Sid and he didn’t have a shirt on or anything. He was just dressed in his leather trousers and he was standing at the door and he let us in and I thought, 'Oh this isn’t going to be much fun.'"
Only it was.
