I'm over 50 and organize a folk club in the USA. You cannot "run" a folk club - you need too much help.
Our problem is that there is such an enormous wealth of talent out there looking for places to play, it makes it difficult to decide who to hire. We try to balance our program between young/older/male/female/traditional/contemporary performers so that we can present the broad spectrum of acoustic music. In the past year 66% of our performers were under 50. 45% were under 40. 17% were under 30.
The music is alive.
