Dave(M): This isn't at all helpful.
I'm not a particularly huge fan of folk clubs, as some here may have gathered.
However I don't think there's any call to name and shame particular clubs you haven't enjoyed on a public forum. What good does it possibly achieve?
I'd suggest that if you want to find out if the club in question is any good, visit it and see for yourself. If you don't want to visit, there's nothing to worry about, is there?
I'd be far more interested in people who believe they run successful, dynamic, thriving and joyful folk clubs sharing their secrets than following your suggestion.
Not on this thread, though.
