I saw Robbie across a crowded pub in Ennistymon, Co. Clare on Friday night - and he disappeared before I had a chance to talk to him. Reliable sources give his age as " 76 give or take one"!.
I've started some enquiries on the source of the tune.
p.s. I believe Robbie is now running a monthly singing session in a pub in Spancilhill - first Friday.
