"people go there to socialise as well, more so than they do with concerts."
NO THEY DO NOT - this is the arrogance of the professional performer - that singing of any worth cannot take place unless they are present"
no, people go to socialise at folk clubs they always have done, that is what a club means, they also go to listen to folk music, they got to meet other people who are interested in the same kind of music., and also listen to that music.
you are the one that has said singing of any worth cannot take place unless they are present, i certainly have not said it, i believe anyone can sing well provided they practise, it is about having a professional approach , not being paid for it.
