They are, indeed, very similar tunes, I think. I should not be surprised to learn that they come from a common source. They are the types of tunes one does not want to play back-to-back at jams, that's for sure.
There are enough differences in melody and structure that they can be told apart, but I'm sure to anyone unfamiliar with the genre, they could just was well be the same tune. But then, that's true of most old-time tunes, isn't it?
I can't get this tab to download into a readable format. I'm going to play this song as part of a final performance at Appalachian State for my Appalachian Strings class, but I don't have tab for it yet. Thanks for your help everyone!!
