Did the two actresses who played "Alice Kramden" (Audrey Meadows during the 1950s, and Sheila MacRae during the revival in the 1960s) and the two actresses who played "Trixie Norton" (Audrey Meadows during the 1950s, and Jean Kean during the revival) really all appear in that season 5 episode?!
Incredible!

No. It was a copy/paste mistake from IMDB on my part. They apparently list all the stars from all the years for each episode for some reason.
