I think we may be doing OK up here - first meet of the month is guest/club night - if we have a guest, they feature majorly, with club support; if not, everyone who wants to has the opportunity to do a (usually) 3-tune floor spot. Second meet is committee night, after the meeting it's singaround, anybody welcome to try out anything they like (to critical(!) acclaim). Sing whatever style you like, blues, jazz, folk, rock - you get listened to, encouraged, criticised; but, above all, treated fairly. Some may not like what you do(who likes everything?), but that doesn't restrict your right to do it. If there's a clique, I've never noticed - if you're an honest performer, they give you due credit.
btw - it's Fyvie Folk Club - advert over!
