Answering Mike's question -
Yes, those were SM57s. The artists insisted on them. They were also singing into their own, 20-year-old SM58s.
How do I know this? I worked the show.
And yes, Queen did sound great! They brought their own backline, mics, stands, IEMs, wireless mics/packs, drum wedges and power cables (all the gear was 220v).
They used the production's SD7 for monitor mixes and SD5 at FOH. Brian May's three VOX cabinets on the floor were double-miced with each cabinet getting a Sennheiser MD421 and what appeared to be a side-address ribbon mic (I didn't get the name or model number of it).
As for the drums, all tom mics and the kick were Telefunken (the FOH mixer was switching from an Audix D6 on the kick to the Telefunken). Snare was an Audix I5. Overheads were c414s.
The bass rig was also miced with a Telefunken top-address mic with which I am unfamiliar.
