So sad to hear of Dave's demise. He was larger than life itself. One of his first ever appearances in front of an audience was in early 60's at one of the EFDSS Northallerton weekends when he completely overwhelmed the rather "staid" folkies of the day with his version of "Johnnie o'Breadislie" I believe these were organised by Tony Foxworthy and there was a competitive element to the weekend. Needless to say, Dave won, and so started his folk singing career. A voice such as his, which could go from being raucous and rough, to gentle and sweet within seconds, is a rare gift indeed.
