Jackie Gleason on segment of the popular 50's TV series "Cavalcade of Stars", doing a sketch called "The Honeymooners", which was later turned into a sitcom. "Cavalcade of Stars" started in 1949 and quickly became one of the most popular shows on The DuMont Television Network. Jackie Gleason was the 3rd and most popular host of the series. "The Honeymooners" started as a series of sketches, and later became a classic CBS sitcom still shown in syndication today.
While the sitcom is still copyrighted, "Cavalcade of Stars" has long been public domain. This excerpt is all I have of the episode (I wish I could see the whole thing! Jackie did lots of different sketches back then). This movie is part of the collection: Classic TV
