What B&W videotapes from 1956 to 1960 still exist?

Hi all. Here's another question following the colour videotapes, what B&W videotapes of the 1956-1960 era still exists?

So far I know these exist:
Some footage of a OB truck driving along a mountain/canyon top with the B&W IO camera on top of the truck taking footage of the scenery [1956/57]
The Edsel Show [late 1957]
Playhouse 90 (various episodes from 1958 to 1960 exist on B&W videotape)
Dinah Shore Chevy Show (whilst in colour, prior to colour videotaping B&W videotaping was used during the 1957 and 1958 period and I assume some episodes exist on B&W videotape, one being an episode which Dinah is singing with Miss Ella Fitzgerald which was shown on her bio on the Biography Channel)
Ed Sullivan Show (I know there are definitely episodes from 1959 and 1960 existing on videotape, I have a 1959 episode in video format, though it's questionable if any 1957/58 shows exist on video)

And over in Australia I think some TV show from 1960 exists on video as I have some real early excerpt of Johnny O'Keefe (Aussie rock'n'roller) singing his 1960 hit "She's My Baby" and the hairdo really shows the era the show's from.

If anyone could add to this list too that would be fantastic.

Cheers
