Oh my. Nigel was the blazing star of the Allan Glen's Skiffle Group when I was 14 and went to school there in Glasgow, and first met the slow-cooking Scottish Folk Revival. Energy, enthusiasm, love of the songs, what a performer. Teacher Morris Blythman captured us all, but Nigel was the exemplar for us. I remember him I think winning his heat at the King's Theatre of the Carol Levis talent show.
Sad news indeed.
