I've just heard that Jim McKenna passed away very recently. Jim was a tremendous singer and interpreter of songs from all genres, and when he put his mind to it, a great songwriter too. He had been unwell for some time, but still appeared from time to time in the Uisge Beatha on Woodlands Road on Sunday evenings. A real fighter!
Here's a Youtube link to him singing Supermarket Wine in Glasgow in 2008.
I'll miss him. So will a lot of people... RIP
