The Sunday night guy on KCSM says that in 1941 a bass player named Chocolate Williams, along with a nearly equally now obscure vocalist Ollie Potter, recorded “There’ll Be Some Changes Made” with Art Tatum. He was working on a segment on Art Tatum groups, a minor part of his oeuvre compared to his solos.

its also true, and perhaps revealing that Terry and I went by 3 times this week for chocolate popsicles from Gelataio on Lytton
Nobody loves you when you are old and gray. I’m just saying.
edit to add, Barbara Feldon sang “There’ll Be Some Changes Made” in the “Casablanca” episode of “Get Smart”.
and1: Billy Taylor, doctor, told Bill Milkowski of JazzTimes in 1991 that Chocolate Williams played at Minton’s a lot, and that was how he got on a 1952 session they were hearing together, a Herb Nichols joint.
In Ralph Ellison’s essay “The Golden Age, Time Past” he states that Charlie Minton the founder of the famous jazz club on 118th in Harlem, at the Cecil Hotel was also the first black to join the musicians’ union (Ellison pp. 244).
andand: backtracking or fack checking, the suss, one finds, via the KCSM Jazz91 site (its Richard Hadlocks show, the annals) and then their link to all music, that you can find these performances on a collection of Tatum:
now i wanna see if its in my hard copy of all music guide, indexed…
(Whitney Balliett, in an essay collected here, called “God” notes that Potter’s singing is off, but he says that only encourages Tatum)
the internet is the ultimate fake book
