I think it must have been about five or six years ago when I saw them. I didn't really know much about them except for 'Tomorrow Girls' which one of the bands I was in used to play. I was pretty well impressed.
They only come out at night, I think. Went to see the UK Subs a few years back - amazing number of middle-aged punks around looking very uncomfortable in all their best punk gear, now about two sizes too small for them!
