Lester Young
The first 4 tracks were originally released on Mercury Records as "The Lester Young Trio". The remaining 4 tracks were released on Norman Granz' Clef Records label as "The Lester Young Trio No. 2" before all 8 tracks were combined and released by Granz' Norgran Records label as "The Lester Young Buddy Rich Trio". Nat King Cole was under contract with a different record label at the time so was credited only as "Aye Guy" on the original Mercury / Clef / Norgran releases.
