Hmm, I'm guessing it's not the one who recorded in the 50s for Jay Miller but he whose recording career began in 1970 under the name of Nyles Jones (actually Robert Lewis Jones, born Florence, Carolina). That year he won great acclaim with a 45 on Gemini entitled The Welfare Blues. He also had an LP, My South - My Blues (Gemini 7101), which was recorded in Pittsburg. A really enthusiastic review by Mike Leadbitter in Blues Unlimited ensured the LP sold better in the UK than it might otherwise have done.
A decade and a half later he reappeared as Guitar Gable recording for Tim Duffy's Music Maker label. I guess the recording of KTTH must be from that latter period.
