I found it. The Original was Sten Kenton Orchestra "Stan Kenton Presents" in 1950. It was a 10" LP and not a 78.
It was later released as part of a 2 CD set called "The Innovations Orchestra"

Be sure to listen to the "MF" Clip if you haven't heard it before.
I'm not really a Maynard fan, but to hear him play in 1950 is pretty shocking.
