I just thought this may interest some people. This is a Guns N Roses show at Wembley Stadium on June 13th 1992. The first link (track 7) is Tie Your Mother Down and the second is an awesome version of We Will Rock You (track 8) ....just when i thought the song was over, a nice twist came, and they rocked it! Brian May played the guitar for the 2 songs. link link
enjoy.
