Yes, I was just thinking the same thing. Joyce Randolph is still alive and she is the last surviving member.
Incidentally, a little piece of trivia. Art Carney who played Ed Norton was living in my current neighborhood during the years he was active as Norton on the Honeymooners. He owned a house a couple of blocks from me and some of the old timers from the neighborhood remember him. He had 2 kids attending the local public school here and he was routinely seen walking to the local New York Central train station in the mornings to head into the city to work on the TV show,
