How much info we have about these three shows?
It seems the venue where Queen played, The Summit, had an internal video circuit, we all saw the video of the '77 gig, and probably Queen were very aware of the situation aswell. So can that 77 show multitracked?
Also, i continue reading there are rumours about two other shows filmed aswell, but sadly, without proof...
Shouldn't someone send a note to Queen Productions, in case they don't know or they forgot, that could be interesting to send someone to investigate the existance and situation of that material?
For the '80 and '82 concerts, the only response you'd probably get is either it doesn't exist, or they lost it.
As for '77, I'm pretty sure the band were very much aware of it, since they had My Melancholy Blues and Sheer Heart Attack from that concert featured in Rare Live as well as the fast We Will Rock You taken from the 1st Greatest Video Hits. Lastly, there's the Bob Harris footages. So I guess there's a possibility they have the multi's.....I hope
I think I mention here a long time ago, that I once spoke to someone who attended either the '80 or '82 show (wasn't sure of the year). He confirmed that the in house CCTV was present and was being shown on the screen.
