Generally closed these days. Folk club audiences don't get any prettier as they get older...

Seriously, I have them open when gigging but to preserve my sanity, closed at singarounds. It isn't just because I'm singing and have a bloated opinion of myself, it's when anybody is singing. It really gets my goat when those who can't be bothered to learn songs sit leafing through their books and iPads whilst others are trying to entertain them. It's as if they think we are all there purely to hear their latest flat keyed attempt at a beautiful song about to be massacred.

I have to shut my eyes because looking at people ignoring you and wondering what they might sing next makes you wonder why they bothered coming. Presumably think people will listen attentively when they are on next... I prefer venues where you can't hear them from the bar.
