This is one occasion where a "stage Irish" song was actually written by a real Irishman; it was popularised by the English performer for whom it was written. Clifton wrote a lot of his own material (sometimes using traditional tunes or themes) but he also commissioned songs from others, and this is one such. I'm away from home just now and can't quote details, but will come back to it in a few days: though I suspect that some details at least are in one of the threads that deal with Clifton and his songs.
