Think I am going to have to respectfully disagree on this. It is still a folk club and as such will have floor spots meted out to members whatever their abilities.

Most of the clubs that I've frequented, since I became interested in this music two years or so ago

By her own admission the OP knew what the potential was before she went and got embarrassed in front of her friends.

I am not happy that there is rubbish going on in clubs and I agree it does give the genre(?) poor street cred. But I can't (or maybe won't in my pollyanna way) believe it is right or good or healthy to exclude anyone (except for BNPers - but that is another thread).
