For 25 years, the Zap club hosted ground-breaking artistic events in Brighton and beyond, starting with its radical music and open-mic nights in the 1980s. For two years in the early days, Roy Bayfield (later to become a noted walker, mythogeographer, performance artist and university administrator) made an art out of his job as cleaner at the club. Here he offers us an "eclectic sweep-up of everything that was left lying around". On one level, it's a memoir for people who knew the Zap club at the time; on another, it's a handbook for anyone who wants to make art out of an unpromising job.
