Wagon Wheel by Old Crow Medicine Show. Fine tip from a friend. Somehow think I should know the song; it's the kind of song that seems to be in your bones already. You can listen to it time and again like you can eat your favorite food again and again. Nicely odd video adds the special element. Perfectly American, yet perfectly not that kind of American. I don't need any more reasons to live there than I've already got, but I'll add this to the list anyway.
