Like Jim Carroll, I was greatly influenced by the music I heard at Harry Boardman's folk club - by 1969-70, it had moved to Failsworth, but then moved back into Manchester city centre. Harry, Dave, Terry and the embryonic Canny Fettle. Last I heard, Dave was definitely in Durham, but not sure about the university lectureship ... in an case, he'd be retired by now. You can find his doctoral thesis on line.
