This duo burned hot and fast and then disappeared, such a shame. I suppose I could've stretched it and used Barton Hollow, that could be a name but it's a place in the context of the song. Gotta be one of the best country songs to come out in the last 20 or 30 years at least. This works. They also did a nice cover of Michael Jackson's Billie Jean from this same show.
I hadn't really thought of it before, but this is a bit like Gillian and David--two voices and one guitar, and that is all they need, nothing missing at all. It amazes me how much noise can come out of one acoustic guitar when you have somebody that knows what they are doing with it.
edit--the guitar does have one of those resonating steel discs, that certainly helps in the noise making department
