Can't help with the chords but I have been known to sing the song.Christy recorded it after spending a day singing and playing with the locals at Tig a Cuinne (the Corner House) in Bradon village, Dingle Peninsula, Co. Kerry. I'm often involved in the Saturday night sessions in that very bar - they can be mighty.
The photos of that day with Christy are fairly poor and virtually anyone could claim to be in them! Two good mates of mine, Eamonn Murphy (Box Player) and Frank Maunsell (Bodhran and vocals) were by all accounts at the session.
