Excellent find, and very interesting documentary.
I remember thinking back in 2000 at the launch, that they must have been in a CGI studio and set, because of that seemingly impossible 'floating desk'. It was a few years later that I discovered the elaborate cantilever construction and fake column/bracket. A truly inspired design.
I'm glad they changed the music prior to the launch. The final version was much better.
It's a shame that the channel lasted a little more than 5 years. Ultimately, it was a project that ITV plc neither had the will nor the money to fund indefinitely.
