Bob Wills and His Texas Playboys made these telescriptions in 1951, and I think this is all of them. Sorry I don't have every musician's name, although I could name the more famous ones. Who knows who "Carolina Cotton" (from Arkansas?) was?
For your listening and *viewing* pleasure, I've made a channel to present some of the wonderful, forgotten rags and songs of the past on piano rolls. The player is a 1925 Cable upright piano (apologies for the bad bass notes and occasional squeaks!) I'm going through the playlist and trying to improve the videos, as well as doing proper scans of the roll labels.
