Shimrod, you said earlier on that you thought I was missing the point of this thread. Certainly I was ignoring quite deliberately one obvious aspect simply because I think that such motivations are not of overriding importance. By this I mean:

(a) those whose sole interest in traditional music is academic
(b) those who think it will singlehandedly change the world
(c) those who just want to sell it.

This is because I think those who sing, play and dance it are the most important. It is with their voices, hands and feet that it will survive and develop or not. And yet it is the music itself which is most forgiving about what is done to it and with it. In Dave Swarbrick's immortal words, 'the music doesn't mind' and in Martin Carthy's, 'the only harm you can do it is not play it'. We get angry about the ridiculous things some people do and say where trad music is concerned but perhaps we are worrying unduly. It's stronger than stupid human mistreatment and will get over it, possibly sooner than we can.
