Ian, can you provide a link to the ITV site? Btw, here's some more facts on lost US shows:
The first two
Super Bowls (1967, 1968) exist only on film right now as the master videotapes were either lost or erased.
Believe it or not, portions of
JFK's inaguration ceremony from January 20, 1961 was broadcast in color on NBC, and the tapes were erased in the 70s, along with most of the color tapes from the 1964-66 pop music show
Hullabaloo- a few still exist and are on DVD.
Johnny Carson was mad as hell over what NBC did regarding his earlier shows. Once he took over ownership of the show, he made sure that everything he did was preserved. So today, practically everything from 1972-92 is in a salt mine in Kansas. Reminds me of when Milton Berle sued NBC over
his lost kinescopes, but they were found at the last minute before the case could go to court.
Also, check out the
Museum of TV & Radio website- scan down to the "Get Involved" section, and there's lists for the most wanted lost US TV and radio broadcasts, dating back from 1920 to the 1980s!

Also, here's a link to a great site regarding the history of color TV in the US- you can see clips from the earliest surviving color and B/W videotaped shows. Here's a hint: the color show starred a Hollywood icon known for keeping the whole world tapping.....
