Old Cow Died in the Forks of the Branch - tab request

This little old-time tune has been stuck in my head for a couple of weeks now. Simple but somehow hypnotic. I first heard it on Clyde Davenport's Clydeoscope CD, and then on Joseph Decosimo's CD:

If anyone can tab this, or get me started on it, I would be grateful. Sounds like two finger thumb lead to me (when Joseph plays it) and maybe index lead for Clyde.
