This show to honor Jerome Kern dates back more the 47 years. It underscores how rule number one for all his arrangers was to keep the piece to 2 minutes or less. It was how he got all the acts into 45 minutes. Clay Hart breaks the theme with a song by Ronny Milsap.
I have no idea why PBS screened this today...Easter Sunday...with so many programs they have in the vault dedicated to the holiday.
