We had two threads (at least) going on this. I refreshed the one and here is a blue clicky thing to the other, with the tune. I'd like to know the answer to Murray's question, too, and someplace around here, I have the original poem, too, if any would like to see it.
Had an interesting conversation with Rick Lee when he came out west recently. He maintains that the two versions of the song tell the same story, whereas I beg to differ. I know they came from the same source. But I heard the long version first, and I didn't find in there any indication that the the maid was given away or sold, or that she it was someone else's bad judgement that caused her to grieve. I kinda thought it was her and the farmer's own bad choice... though I don't think the poem tells us. Just "He stole her from her tinker kind, and on the morrow they were wed."
The short version of the song has her father trading her for a pony.
Blessings,
