Yes; it was from Cathal's singing that I first learned it. It's particularly interesting that the song seems to have undergone so much variation in a relatively short space of time. Many thanks to Martin for posting those turn-of-the-century texts. There must be earlier examples out there somewhere (and, you'd think, some with music; it clearly began as a parlour ballad) but I don't know of any yet. With luck, further information will turn up.
