How sad, even though I didn't know Jacky. Far too many 'Obit' threads turning up on the Mudcat, and each and every one a great loss to a great many people. RIP.
Jim, do you happen to know if Jacky took part in Gordon McCulloch's 'Glasgow Eskimos' show that was staged during the Glasgow Folk Festival about ten years ago? A tall guy with a good tenor voice (I think). If so, I saw (and heard) him that night, but never before or since.
