"MacColl's demolition of a songwriter at the Critics' Group, that was aired on Radio 4 a while ago".
Having gone through all the tapes (1964-1971), I found virtually no examples of criticism of anybody outside the Group - that isn't what it did.
I spoke on the Group during the symposium for MacColl's 70th, and one of my main criticisms was that they isolated themselves from the rest of the revival, rather than trying to influence it.
That didn't mean that members, MacColl included, didn't have opinions on individual performers or clubs, nor did it mean that they didn't express their views during the meetings, but we were there to work on each others singing and to explore different aspects of the song tradition
