Hey greg, some of those self-same clubs were actually started "by people playing new forms of music".
There are some hereabouts who seem to be trying to perpetuate the myth that if clubs had stayed traditional then there'd be one on every high street today, bursting at the seams. Get real!
If, like me, you want folk music to be around in 100 years' time, then you need to ask yourself just why the "proportions of the new music outweighed the the original" because therein lies the key to its survival.
Adapt or die.
