Just got an e-mail from someone wanting to know what's with the weird commercial in the Our Place episode in the previous posting. I think this is a transfer from a 16mm print made for overseas distribution, particularly to our Armed Forces stationed God-knows-where. For these films, the original commercials were omitted and sometimes, special ad spots for servicemen or U.S. interests were inserted.
As you may know, a lot of great old TV shows were lost because someone decided to save cash and/or space by erasing the old tapes. Most of Johnny Carson's early years are gone because of this, as are many, many other shows. A few treasures of television history have managed to survive because an old 16mm print of an overseas version turned up in a closet somewhere. I suspect that's how this episode of Our Place exists at all.
By the way: I'm not quite back yet but hope to be, some time later today.
