Oh, boy. Here's an amazing bit of video: An episode of The Admiral Broadway Revue from February 11, 1949. Most homes in America didn't even have one of those newfangled television machines on that date but the ones who did could watch this show starring Sid Caesar and Imogene Coca. This was Sid's first series, the program that turned into the famous Your Show of Shows. Howard Morris and Carl Reiner were not a part of this endeavor.
The Admiral Broadway Revue was produced, directed and co-written by Max Liebman alone with two other writers — Mel Tolkin and Lucille Kallen. It was done live from New York on Friday nights, airing simultaneously on both the NBC and the DuMont networks from 1/28/49 to 6/3/49 so this is the third show. At some point during its run, Caesar began paying money out of his own pocket to a kid named Mel Brooks to help punch up the scripts. We don't know if that had happened yet.
It's a pretty good show…and a pretty good kinescope. You might want to watch a little of it if not the entire thing…
