I suppose it started in London, in that bogus Greek taverna in Battersea Park Road, with lunch on Cohen’s corporate tab. Dead steam-table food and it took them thirty minutes to find an ice bucket for the retsina. Cohen works for Barris-Watford, who publish big, trendy ‘trade’ paperbacks: illustrated histories of the neon sign, the pinball machine, the windup toys of Occupied Japan. I’d gone over to shoot a series of shoe ads; California girls with tanned legs and frisky Day-Glo jogging shoes had capered for me down the escalators of St John’s Wood and across the platforms of Tooting Bec. A lean and hungry young agency had decided that the mystery of London Transport would sell waffle-tread nylon runners. They decide; I shoot. And Cohen, whom I knew vaguely from the old days in New York, had invited me to lunch the day before I was due out of Heathrow. He brought along a very fashionably dressed young woman named Dialta Downes, who was virtually chinless and evidently a noted pop-art historian. In retrospect, I see her walking in beside Cohen under a floating neon sign that flashes THIS WAY LIES MADNESS in huge sans-serif capitals.
