Well, have been to one or two folk clubs elsewhere, so assume singing and music by whoever is brave enough to perform/knows the words. That about right? I just wanted to check it wasn't more akin to a friends' get-together, that's all.

Would it be OK to bring teenage children - promise they'll behave, even if the younger one, being high-functioning autistic, is a bit apt to chatter on in a monotone unless warned - he does like folk music though, and sat through a three and a half hour session at Walthamstow Folk Club with only the occasional faux pas.
