Cyril Fletcher, the old fruity TV presenter, teaches cultural studies. We are getting on well despite my being a little nervous of him because I rarely understand art theory. He takes my arm and we look at the cardboard entrance to a performance. It is dark and hung with what looks like a Sickert style portrait. "It's actually a photo," I explain, "blown up really big so it has become pixellated and distorted." We both agree it works well. Cyril is very sugary but kind of fun to be with.
