I've had two Queen bootlegs named "Carnival At The Court", although they were copies and not the original silvers. One was an audience recording, which I owned ages ago, and the other was an audio rip from the widely circulated video. I believe this to be the Masterstroke version, and I think it comes with a DVD (I didn't have the DVD). The audience recording wasn't the best I've heard - if my memory serves me correctly, it had a lot of distortion. The "Soundboard" version was OK. I don't have either anymore - the first I threw away and the other I lost in a house-move.
I am afraid I know what it is :-( link link
The tracklist of the video looks like the tracklist of the 2DVD video I shared here. The front cover looks like a screenshot of the menu of the DVD :-( I hope I'm wrong, but I'm afraid it's the same case as with the Hammersmith Odeon '79 release :-(
