Troy,
One of the best sites is;

belonging to Kris Trexler. That camera was a workhorse for RCA only because it's successor, the TK-42 was a dog. One IO and three vidicons for a color smear. Norelco had come out with the plumbicon (lead-oxide tube) and it's color killed anything RCA had. CBS in the mid-70's bought a boatload of Thomson plumbs and the color was spectacular.
The Astaire show you mention is not commercially available. It is restored and belongs to the UCLA Film Archives. I am not sure about the Eisenhower show. Lot's of others, though slightly later exist. Check Amazon.com for Judy Garland and The Bell Telephone Hour. Some early color from the 60's in those two.
