Well, I met Ewan MacColl twice. Once, Enoch Kent rather wickedly introduced me in the darkness -I was sat in a car, Ewan MacColl was stood outside - as 'another Ewan', which rather startled MacColl.
Another time we briefly conversed across the width of a venue where he and Peggy were sound-checking. I learned with astonishment that he and Peggy had learned and sung my Shift And Spin song for a workshop. I had made a few versions of the song for different shows, so asked which version they had used. MacColl was again startled - why had I changed it?
In addition I had various correspondence with both, mostly via Peggy. They were unfailingly polite and encouraging re various projects, and gave a very fine commendation quote for me to use for the Scottish CND Buskers cassette.
