Weenie Campbell has a Howell thread, with collective decipherment of many of his lyrics, including "Coal Man Bls" (first hit off the bat, initiated by John Miller). Also much info on Howell's keys and guitar tunings, for those who want to replicate style as well as songs. This site is a MUST for anybody interested in country blues lyrics and licks, not to mention general BSing about the subject.
