It's for everyone who's interested enough to attend IMHO. There's room for give and take, as there's also room for different styles. Occasionally you'll get a dog performer, but that's OK - I bet 200 years ago when the old boys were singing the old songs in their parlours or in thge local they had crap singers too, but the music survived OK.

Everyone who performs had to start somewhere - they were all crap at the beginning (I dare any performer to claim they've always been fantastic). Folk-club attendees are, in the main, amazingly tolerant and will forgive the odd bummer.

If you get a performer who's, shall we say, of limited ability, and the listeners take umbrage, it's more a comment on the listeners than on the performer.

Just my view.

See you toneet,
