Listening to some other Louvin Brothers tracks, they really have completely dissimilar voices, don't they? One of them sounds a lot like Roger McGuinn, the other like Laura Cantrell or someone.
That's not my favorite Uncle Tupelo, but it's a nice one (and certainly one of their more trad-country songs).
I have a Jason and the Scorchers album somewhere, but I never listen to it. I like this John Denver cover but I'm not sure anything country has remained of the original.
