Strange indeed. From what I remember about the sound and feel of the recordings, those dates seem plausible.
My copy of Bruyninckx shows Creole 1 (Slow Blues) as from 1943 with Burke accompanied by Vic Colin (Accor), Bob Thompson (g), and Jack Sheehan (d).
I don remember an accordion on that title. I'll have to play it tomorrow if I can find it easily.
Mine is Creole 1, but it has the same titles as your copy of Creole 3. I just took a look at the Lord discography, and Creole 2 is listed, with a recording date of 1948 or '49 (I've already forgotten which). Creole 3 is not listed, but like I said, it appears to be the same as Creole 1.
Independent labels move in mysterious ways their wonders to perform.
