Here we see Bing and Satchmo performing their duet from "High Society" for The Edsel Show. One noteworthy tidbit is that we only have this videotape because it was performed live and videotaped later to be broadcast in the Pacific time zone. If it wasn't necessary to record it for that reason, we wouldn't have this clip today.
The Band here is a little different from the movie. In addition to Bing and Louis we have:
Trummy Young - Trombone
Edmond Hall - Clarinet
Billy Kyle - Piano
Barrett Deems - Drums
