Sheer Heart Attack is mislabeled as We Will Rock You (fast) on the FLAC version that's been going around in the hub (and who knows where else). They definitely played SHA on the second night.
As for the end of the show, as far as I know the genuine recording cuts out part way through Champions. Any version with the rest of Champions and GSTQ is a splice from another show.
Hope this helps !
