I go to two folk clubs in SW London on a regular basis and the audience and performers are all over 45, most are older. There are a couple of clubs which have one or two young, teen & 20's, performers, but they all seem to play self-penned acoustic, pop inluenced stuff rather than folk. Some older folkies drag, and I do mean drag, along their kids, but personally I feel sorry for kids who can't find somewhere of their own making to go to. If you want to see younger performers & audience you have to go to the festivals. We in my local clubs all seem to have moved on together in a time capsule set c 1970! :~)
