That is....assuming it is a paying audience. The ones I go to, I never pay, other than a raffle ticket and a drink. I get to play a few songs, and listen to others, and give support even if I think sometimes it could have been better. It just depends what you want out of a club.   And for me, it is not listening to one or two acts all evening, and not being able to sing myself.   Seems to me that such a scenario is a poor description of a club.
