The Duke and the Cat.

Apparently William Alonzo "Cat" Anderson's trumpet register closing "Rockin' in Rhythm" was so stratospheric that the film director didn't even hear it, and so he failed to zoom in.

I prefer the version of this song found on Duke Ellington's 70th Birthday Concert, which probably lies near the top of my "favorite big band album" lists. For the incredible Anderson showcased to far better effect, listen to "Satin Doll" from the 70th birthday concert -- but be prepared for neighborhood dogs to bark.
