I posted this to  a jazz research list serve and got no response.  Maybe someone here knows. On a Jazz Club USA broadcast from (I believe) 1952 devoted to Arnett Cobb and Lester Young, Leonard Feather announces that Prez was recorded at Birdland and that his band consists of Jesse Drake, Earl Knight, Lee Abrams and Gene Ramey. However though all these players were in the band around the same period , neither of the 2 Prez discographies I own show them all in the band at the same time.
