More early colour TV show questions

[Aussie Bloke]

Hi all. I've got some more questions in regards of early colour TV shows.

Now looking at this page on Ed Reitan's site http://www.novia.net/~ereitan/rca-nbc_firsts.html "The Esther Williams Aqua Spectacle" broadcasted on 29th September 1956 was recorded to colour film using the lenticular process. I am wondering does this film still exist and has there been any way of transferring/restoring this film to digital like those 1954 colour kinescope recordings as I read somewhere on the web in the past that there hasn't been a method developed yet to transfer lenticular colour films?

Also is there any other 1950s colour kinescope films recordings of TV shows out there?

And here's a rather bizarre question. I'm aware that the Milton Berle Show was in colour in the 50s, well maybe for some specials at least. Now I've seen a couple of Elvis Presley performances on his shows http://www.youtube.com/watch?v=YOcGOPY0n3w and http://www.youtube.com/watch?v=saJw_7APQ8E and I have a feeling those shows were originally done in colour. Reason behind this is that I've seen B&W kinescope clips from both B&W and colour shows of the 50s and it's pretty simple to distinguish between the two as with B&W cameras there's halos galore even with not so bright objects and with colour it takes brighter light to give off a halo due to the colour filters in the camera reducing the light to the IO tubes and so the pictures look more normal with hardly any halo, and in the case of these two classic Elvis performances there was no halo in the studio clip and the outdoor clip on the ship there was some halo when the guitars reflected the sunlight. So it brings me to this question, were these performances originally in living colour?

And stemming on from the Elvis question is another question, who was the first rock'n'roll singer/band to appear live in living colour? So far the earliest confirmed colour rock'n'roll performance is the Everly Brothers performing on the Tennessee Ernie Ford Show in 1961 which I have on DVD, and the colour is nice too.
