Charles Brown has all too common a name, and it can fuck up discographers. Tom Lord's jazz discographical data bass has Charles Brown who played congas on a Coltrane session, and Charles Brown who played tenor sax with the Detroit Jazz Composers orchestra, both cross-referenced to Charles "Drifting Blues" Brown, obviously mistakes.
But then he has T-Bone Walker leading a group of jazz all-stars in 1973, with Charles Brown listed on organ, again cross-referenced. Another mistake? Lots of piano players also play organ occasionally, but I never heard of my Charles Brown doing it. And this is an all-star jazz band, not his normal company, although he did play with jazz musicians occasionally. On the other hand, he and Walker are both blues guys, and both veterans of the Central Avenue scene of the 1940s, so I guess it's possible, Two friends are on the session, including Warren Bernhardt on piano, and I could ask them, but they're both dead.
Any ideas?
