Forrest Sawyer is simply too young to be this person. He was a teenager when
this clip was recorded.

There are no credits on the material, even the one from 1978. It was not
done back then for this kind of material. I’ve dealt with a number of them,
and only the author of the text was credited, for some reason.

You’re right about academic narration. I’ve checked Archive.org, but it
turned out to be like looking for a needle in a haystack. Too time
consuming. I’m hoping to find someone who was involved with the recording
process at the time or somebody who knew this person.
