In my opinion, the best folk clubs are those that offer a wide variety of music in the (for want of better words) folk idiom (dons hard hat and waits for the missiles). I suspect (and I'm sure Banjiman will correct me if I'm wrong) that this makes for a successful club because it has the widest appeal. If I were to go to a club where only traditional songs were sung I would soon get bored and would probably not return. I suspect that this would be the case with many folk fans.

Something for everyone isn't a bad maxim in this, as in so much in life.
