I have found it in a book published in 1920: Ar gCeol Feinig. It was published in Dublin. All the songs appearing in the book were collected by a priest, an tAthair Padraig Breathnach. This particular song was collected from the singing of Nioclas Toibin, of Ring, County Waterford. Anyway, Father Patrick goes on to write what a wonderful singer Nioclas is and that this song is one of maybe ten more that Nioclas sings in the same vain.

Hope this helps. I'd sing it for you but I don't want to inflict pain on an innocent man.
