I've had this tune and chord progression bouncing around for years - at least 15, by my count. Gathered with a group of friends last spring in the north Georgia mountains, I strummed the chords for a while. This is what emerged. Now: I've recently gotten a copy of Mac's Garageband software. It's addictive. So this is my amateur attempt at arrangement. Enjoy!
