Stuart, this is absolutely brilliant! As someone who has been listening to this song for about 40years its nice to know who is responsible. I remember my brother in law, the late Tom Munnelly, singing it for a long number of years and not being sure who was the originator. Dave was (and is, I'm sure still!) a superb singer. I remember himself and Derrig Monks in the back lounge of O'Donoghues and The Neptune.
