I agree to a point, made the round trip to London and back a few years ago which ended up a waste of time. Played to three people and a dog. Our mistake wasnt going down there, it was that we were disheartened by it, didnt put on a show. Amazingly the three people were impressed but we had nothing to sell to ensure the next time we went back those three people would be there again, but with their mates. (hopefully!) So we failed to capitalise on the situation. Didn't even buy a bone for the dog so at least he would be back the next time we played. Never played Dirty Martini's, played some other dive in Kilmarnock years ago, not even sure its still there. But earthing problems don't sound good !! "Gig Lots, but Gig Well" - that's a good philosophy to have.
