I'm not claiming any virtue, I'm no angel on these things. These seem to be new remasterings for JSP by Ted Kendall from 78s etc. from collectors. It doesn't seem to be a rip from someone else's remasterings. They're presented chronologically and I think they sound better than the King Jazz and the RCAs I've heard.
So. . . I don't think they stole these, I think these are their productions, and yes I wanted to have a comprehensive Waller cd collection, didn't have all the RCAs, and I went for it. If I felt these were just remakes of the RCA boxes, I'd look for those. . .
