Stopstart,
From your description it appears that you have a re-mastered version. The Phil Collins bit was done by the TVAM team first and elicited some mock sulking from the Jag mates. To be fair, the TV guys took their camera to just about every bar in the place and seemed to end up in their rooms showing the video from the same evening. So doing some quick editing and adding music was a doddle for them. Anyway, the next thing we knew they'd done the Whitesnake bit (shame about all the Bucc footage, but there you go ;-) wrapped it up with a few out-takes and general mucking around.
It was never an 'official' piece of work and never distributed other than by mates.
As an aside, if you watch the GR1 bits closely, you'll see some AAA appear.
Cheers
