I think I have exactly what you're looking for. The problem is: It's all in my head, no music or tab. I learned it from Steve Kaufman's "Arkansas Traveler" CD years ago. Check that version out, it's pretty fancy but the chord progression is what makes it in my opinion. There was never a lesson or tab for that as far as I know. If I could put it to paper for you I would but that would take forever and I wouldn't know how.
I guess the only thing you got from me is a version you might like. Sorry I couldn't help you more.
If you want to try and learn it by ear, it starts out in G and later moves up to A.
