My concern is that some situations purporting to be a Folk Club isn't, A team of musicians having a session in a bar could be a Folk Club
A pub having a spare room and paying for musicians to entertain the public is money for the musicians (who are entitled) and beer sales for the pub is just that ~ pub and audience are entitled to good quality entertainment, but it brings up the question of audience behaviour/use of pa etc and a host of other things
Folk is to be listened to, pubs are where people go to talk and let off steam (hence folk clubs in quiet environments)

I would simply say watch what it is you are trying to do, enhance pub beer sales, give work for good musicians or run a folk club, and yes I know all three, but have a concern for the quality of material which is Folk Art

Not that you need it but you have my full support for your new club in Barnsley ~ but be careful what you are taking on!
