@hightor,
I remember all except Fred Sayles. I have a specific memory that I was watching Claude Kirschner as a very, very small child when it first occurred to me clearly that death is inevitable and permanent. I had, of course, already known it, but that was the moment when I really got it.
Soupy Sales went on to be a regular on the reboot of "What's My Line." I believe he had been on the original show a few times.
I heard that one of the reasons we don't see re-runs of "Sky King" is that many episodes were lost in a fire.
Recently, a YouTube reactor reacted to "Superman: The Motion Picture." She said something like "Christopher Reeve was the best superman. Prove me wrong." I said, "I think George Reeves from 'The Adventures of Superman' was the best but I can't prove you wrong because most likely you won't look." She replied "Challenge accepted!" However, it seems as though she actually did not look because I could never get her to reply about it again.
Speaking of things that younger people don't know, did you like the real "Avengers?"
