I need to check this out, but I think this may be a song by Barry Moore (aka Luka Bloom), if there was a lot of harmonica on it that confirms it for me. If its the one I'm thinking of he goes into Danny Boy (the first version of I ever liked) straight afterwards.
The song is recorded on an album called 'In Groenigen' (sorry if my Dutch spelling isn't the best) which he made in the early 80s with, among others, a harmonica player called Eamon Murray, while he as still called Barry. I used to joke that the album was about toe-nails (think about it!) - which says a lot for my silly sense of humour.
I'll dust off my vinyl (struggling with spelling here again) over the week-end and get back to you on it.
Barry (Luka) wouldn't be classed as being part of the Irish C&W 'tradition' though.
