It seems my copy is slightly more complete than the one posted by Great Wizard. At least, it has complete White Queen and Somebody To Love. '39, Jailhouse Rock and God Save The Queen are still cut. The cut in JR and GSTQ are probably from the original tape but the cut in '39 seems very strange, like a skip from a CDR and probably won't be there if a tape is found.
Note that I've not compared the two recordings from the beginning to the end so there might be some minor other differences between both.
Anyway, here it is as good as you can get:

Comments: Pretty good recording of the Day At The Races Gothenburg show. the four first tracks and Now I'm Here are worse quality than the rest of the show. Some speed issues here and there. Sir Gh shared a copy that are missing some bits but this copy seems slightly more complete.

Your copy is identical to mine in sound quality, except it's just a bit louder.
The complete intros of White Queen and Somebody To Love are there, so I just mixed them into my version, speed correcting the latter since the good-sounding part of the tape runs a bit too slow.
I'll update the original thread with a fix.
Thanks for your help !
