I too get Vic and Tina's email listing, even though I'm nowhere near Lewes, I skim through it every monh and think, "Yes, I'd like to see x/y/z; Grr, wish I lived in Sussex!"
But I'm willing to wager that Lewes is one of those exceptions that proves the rule (in the poper sense of 'proof') that folk clubs, as a breed, are on the decline.
There's nothing Jim's said all the way through with which I can argue.
