Jackie Gleason's String Orchestra with Bobby Hackett trumpet - I'm Through with Love
I know Jackie Gleason as a comedian and actor, but evidently he was also a musical guy, popular enough that his tunes came to be known as 'Gleason make-out music'.

Reading a little more about Jackie, I came across the Eletronicam, which was used to record the The Honeymooners.

JACKIE GLEASONS'S "HONEYMOONERS" is filmed by Du Mont Electronicam System which incorporates an especially desined and adapted 35 mm Mitchell movie camera. Here are Jackie Gleason and Joyce Randolph, right, peering throught the camera lens at Audrey Meadows and Art Carney.

Some people went to a lot of work to put this machine together. I guess television advertising was really paying off. Here's a brief magazine story about this contraption. It's a scanned PDF, but you can enlarge it enough to make it legible. American_Cinematographer - March 1956 - Arthur_Miller Looks At Electronicam

Coincidentally, just a couple of days ago I posted Veritasium's History of Video.

Mitchell Movie Cameras have shown up here before.
