Dave,
I see litle point in continuing a discussion with anybody who believes 160 Folk clubs represents a healthy scene - especially as most of them have little to do with folk song proper
Your definition is the 1954 definition which, for all its weaknesses, bears no resemblance to what happens in the majority of your 160 clubs in your healthy folk scene.
I see little point in all this - when I get time I'm going to deal with Howard's earlier posting amnd his interesting question on the toxic thread
Jim
