In 2006, MPI put out the Color Honeymooners Collection 1. It had one bonus feature entitled the Great Gleason Express which is 7 minutes long. Here is some footage taken from WTVJ (now an NBC station) in Miami.

Awesome footage! Must've been the partying, I guess but, in the train during the interview, if Gleason's hair had been grey he would look exactly the same as he did in the much later 60 Minutes interview.

Aside from Gleason, just think of all the other great TV entertainers we had during that classic 1950's and 1960's era. There was Bob Hope, Jack Benny, Sid Caesar, Milton Berle, Ernie Kovacs, Danny Kaye, Dean Martin, Red Skelton, just to name a few. There will never be entertainers like this again and that era will never be duplicated.
