Dear Bill D. I heard someone sing the song years ago. i got the words and fitted the half remembered tune to it. Later I heard the original version by Red River dave but decided to stick with the way I was already performing it. It is not commonly sung in the UK as far as I can tell therfore the expectation of a particular tune may not be so great.
I was singing it in a pub recently and a man form the performing rights society was there taking notes. When he asked who performed it I told him it was Red River Dave the yodelling cowboy; I think he thought I was pulling his leg by the look he gave me. john
