Michael Cross does of version of this song, which he calls Elma Turl.

Elma Turl was a beautiful girl and I'd like to have her for my wife.
She's just the kind of a woman to make me happy for the rest of my life.
My Dad said son there's something you don't know, and it's something that I think you oughter,
Elma Turl is a beautiful girl, but son, she's my daughter.
More words if you want them.

If you are also looking for the Randall Knife, it was written by Guy Clark. I could probably dig up the album and the publishing info. if you want it.
