“hard to believe that any of them were still alive”
The original Trixie from the original sketch was Elaine Stritch, she played Trixie just that one time in 1951. The classic “39” episodes from 55-56 Trixie is played by Joyce Randolph, Both are still alive according to Wiki.
interesting tidbit
Also why is there not a TV show that goes out and interviews these old stars before they go away?
