In the 1980s Bob Mazzer worked as a porn cinema projectionist, first in King's Cross, then in Paddington. He lived for a while with his father in Manor House, and then got his own place in Archway. Naturally enough, he travelled to work by Tube, returning late at night, due to the nature of his job. "I felt the Tube was mine," he says, "and I was there to take pictures. It was like a party."
