I have been to quite a few folk clubs in the last few years. Some times they are run by the Old timers but the audience usually has a few young people too. The places that seem to do best are the ones who include a bit of Blues, Jazz and C&W as well as traditional Folk. I would travel to any venue that had Harvey Andrews or Winter Wilson or young David Gibb. Others have their favorites and most of these venues get by between big name by playing songs they like and know well and generally end up being Folk playing and singing music they like. Even if its not called a folk club the essential ingredient will still be there
