I don't know.. there are many great shows.. one of my favs is Oakland 1978.. I think it was Dec 16th not sure at the moment.. but of course my ALL TIME Fav is the one I was at, but unfortunatly there is no boot of that available, so the next best thing is Chicago Sept 19, 1980 the day before I saw Queen.
From the concerts that I have heard, I would have to choose between the following concerts, which are the best I have heard from each tour.
Buenos Aires 81-unsure what date
Not the debate I know but the worst sound quality awards:
Brian's guitar sounds like poo on the whole magic tour (TURN UP THE OVERDRIVE BRI!!!) so that whole tour is out.
The Montreal DVD has amazing sound except you can't hear the bass.
The least said about the Mercury tribute gig the better!!! TURN BOWIE's SAX MIC ON PLEASE!
The best sound is IMHO: Xmas eve 75 and Live Killers
Even though there isn't a boot of the Omaha show I was at, the Milwaukee Sep. 10, 1980 show from 3 days earlier is pretty good. I just ripped it to mp3 from my CD and put it on the hub. (I have the 2-disc version which is longer and better quality than the single disc version. I hardly see this show on the hub at all though.)
At the end of Fat Bottomed Girls, Brian announces he just heard The Game hit #1 "with a bullet, so I want to say thank you to you." This show seems to capture some of the crowd's energy that week. "Crazy" had just been at #1, and "AOBTD" was about to be #1, so this was taped during Queen's peak in the US.
Also, I like the version of "Save Me" on the Milwaukee show...they don't sound bored when they do it. :)
