Totally agree with what others have said, it's v badly filmed and if no other versions exist then it should remain condemned to Queen's video vaults.
Also, old father time is catching up with some of the 70s concerts. As each year passes the more dated and more naf some of them look. (same with the 80s!)
Like everything else, they only have a certain 'shelf date'.
Old fans like me who were around in the 70s and 80s are not getting any younger!
They had and missed their chance with 'DVD boom' in the early 2000s.
I agree with KevoFM about how QPL should have pulled their fingers out with DVDA & Blu Ray, but personally i think 70's PAL SD filmed on 2" video tape hasn't been beaten for quality yet. Sure, HD is a nice clear picture and obviously twice the resolution (or more?), but the colours and the interlaced look of 2" videotape is beaiutiful and sorely missed.
I am running out of life and there is still much unpublished material. What exactly is Queen trying to accomplish by keeping the archives under a lock and key? Release the thing in stereo. it does not have to be in the blue-ray UFO technology format. In the end, I am preaching to the choir...
