Anglo, I wasn't suggesting that the three names I gave should be a definitive list, to the exclusion of all others. It was because someone up there remarked that few people had heard of Martin Carthy that I mentioned him and the other two, off the top of my head, as an examples of "revival" singers who deserve to be better known outside the folk world. Of course there could be a place for the "source" singers and musicians too, although there is less good quality recorded material to draw on, which could be a problem.

Of course there would always be disagreements about what should/shouldn't be included in a core curriculum, but that's no reason for never attempting it. Whatever was decided would have to be provisional and flexible, so that the syllabus could adapt to new ideas and suggestions as it went along.
