In 1983 I was sent to New York to interview Johnny Rotten and I took the opportunity to call on Andy Warhol. The Factory was in the phonebook; and the receptionist, Brigid Berlin, said that Andy was in Milan but would be back the following afternoon. ‘You better give him half an hour. Why don’t you come over at 2.30 p.m.?’ So I did. I’d never been part of that New York scene, but wanted to meet someone who had helped me develop my own freedoms almost 20 years earlier. According to Blake Gopnik’s book, I should have found a studio that was triple-locked, with an anxious artist hiding inside.
