Not that it solves anything, on the contrary, but Michel Ruppli's discography "The Aladdin/Imperial Labels" (Greenwood Press, 1991) gives this info, which is roughly the same as the earlier discographical data provided by Bruyninckx et al:
WYNONIE "Mr. BLUES" HARRIS AND HIS ALL STARS:
Wynonie Harris (vo) with unidentified orchestra (similar to November 30, 1946 session).
NYC, July , 1947
A-4025-3 You got to get yourself a job girl Aladdin 208; Route 66 (sd) KIX-20
A-4026-1 Hard ridin' mama - ; -
A-4027-1 Big city blues Aladdin 196; Route 66 (Sd) KIX-3
A-4028-1 Ghost of a chance - ; Route 66 (Sd) KIX-30
I guess the discography in the biography is the most trustworthy for the reasons Steve mentioned.
