It is difficult, sometimes, to convey things in writing without making them sound challenging. It is much easier to convey this by tone of voice in conversation. I write this with the hope that it will not sound as though I am trying to start a row - which I am not......

Jim wrote
he adopted an isolationist policy and worked with those he believed could make a difference on the folk scene

Then he quotes me agreeing with him saying:-
If he had tried hard to explain his views on the tradition in a better way to a wider audience, his impact on the folk scene

and responds this by saying -
You're assuming he didn't try Vic

Well, which was it? Was he trying to disseminate his views or was he being isolationist. I don't think that you can have it both ways.

And one more thing. You explain Ewan's attitude to other performers.
I honestly never heard him take a pop at any other performer - not publicly anyway, and certainly not in the period I knew him.
Utterly admirable! A policy that many would be advised to adopt, because in the end it is only personal likes and dislikes that we are talking about. It would be good advice to someone who has in recent times 'taken a pop' at artists as diverse as Jeremy Taylor and Norma Waterson on the very public forum of Mudcat.
