Thanks for the info, Guest and Guest M.

I thought I'd try to get the right lyrics from that video, but I give up. Sometimes the words are completely unintelligible. And the melody - hard to believe that a simple country person created that.

I found a tune on ABCnotation.com that seems related, and it's free of the copyright problems that I find with Niles' things. I've made a MIDI of it and will transpose it down. (The highest note is the A above the staff. What!?)
