The information about "What-Cha-Call-' Em Blues" having been issued on OK 4051 came from two sources.
1. The redhotjazz archive at http://www.redhotjazz.com/palledo.html
2. The useful compilation "Early St. Louis Recordings" by Joel Slotnikoff and Deborah Hyland in http://www.bluesworld.com/StLouisDiscogEdit.html
Both of these are in error. Rust had it right.
