There was a programme and it did have such a section in it, a point relevant to the discussion on this thread of female singing styles and also to the discussion of 'revivals'. For me, stating this fact is not 'showing one's ignorance'.

My understanding is that we are being told that MacColl was a significant figure in preserving English/Scottish (possibly Irish, not sure about this but he does sing in an Irish accent on one song on Spotify) traditions. I am merely asking for an example.

I am perfectly happy that nobody should regard me as an expert: it is precisely because I am not that I have delved into the works of Roud and others and engaged with the ideas that they present.
