I used to enjoy clubs, but carefully vetted for music and decent people. So maybe a bit like gigs. The Banshee in Manchester put its entrance up to 1p while I lived there. I met my wife in a nightclub too. Though the incomprehension Ian mentions creeps in occasionally.
I went to a club in London a year or two back, to see Kieran Hebden DJ. It was good fun, though I did feel a bit old and needed my bed by 2am, though the rest were still going strong. So maybe middle age is creeping up on me.
