I love the concept here 'Spaw.

One song is pretty difficult, but I'll stake my claim on Doc's version of Deep River Blues which is a derivative of Rabon and Alton Delmore's Big River Blues.

Doc's early flatpicking was inspired by Rabon's hot lead playing on a tenor guitar (a Martin O-17T I believe) and over time he adapted it into the fingerpicking classic "Deep River Blues". I think this is one worth preserving and I think I may have to put a version of Doc performing it (vocals and all) on a micro CD, (concealed in my key chain) because nothing can mimic the voice he lends to this song.
