I have been listening to the 1993 Documents release "Alabama: Black Country Dance Bands 1924-1949" (DOCD-5166). Most of the artists included only have a tangential relationship to Alabama; Johnny "Daddy Stovepipe" One consistent aspect of all these sides is that the instrumentation is for either banjo or mandolin and a harmonica; Documents' annotator further ascribes the harmonica in the Grafton session to King Solomon Hill
This refers to the DOCUMENT label; they are noted for reissuing the work of artists in complete chronological order. This should NOT be confused with the "DocumentS" CD label, which seems to be a product of the German "Membran" operation; this latter label puts out 10-disc sets of 200+ tunes, often copying material from already-issued (by others) LP's or CD's...these sets sell for $20-$25, sometimes less on the net...!
