JAB, I have checked out the sites you mention. I have all the Nugrape CDs which are excellent musically, but devoid of any notes or adequate discographical information - mostly black gospel and early country. The Nugrape site has some excellent links.

I don't think you will find much, if anything, on the net about the Georgia Yellow Hammers - Dale Rose would know if anything at all exists. If you have access to a decent library seek out issue # 25 (Summer 1977) of Old Time Music. It is a special issue on old time music in Georgia. An article therein by Gene Wiggins and Tony Russell 'Hell Broke Loose in Gordon County Georgia' gives excellent info on the Hammers and others.
