Rather than just making lists of names - why not actually look at some of the blues that these people actually recorded? In the 1920's and '30's there were a goodly number of white blues recordings (not all by people who were born before 1895), so why not talk about these. You could look at 'K.C. Blues', 'Worried Blues' & 'Cannon Ball Blues' by Frank Hutchison, 'Mistreated Blues' by the Carolina Buddies, 'Ash Can Blues', Chicken Roost Blues' & 'Tom Cat Blues' by Cliff Carlisle, 'Lonesome Weary Blues' by Roy Harvey & Leonard Copeland. Then there is Clayton McMichen's 'Prohibition Blues' or Larry Henley's 'Matchbox Blues'. The list just goes on and on.
'Matchbox Blues' seems to be a straight copy from Blind Lemon Jefferson, but many white blues cannot be so easily traced. So, I repeat, why not look into the blues themselves, rather than just listing the names of singers and musicians (some of whom seem to have had very little to do with the blues.)
