I have already upload these files on the next day after Queen's performing on Russian Music Awards 2004 on October 16th 2004 in the State Kremlin Palace, but since those links are no longer available and maybe someone's interested to hear this stuff, here we go!
We Will Rock You (Brian - guitar, Roger - drums, Mger from the cast of WWRY-Russia - vocals, the cast of WWRY-Russia - backing vocal)
We Are The Champions (Brian - guitar, Roger - drums, Zemphira (Russian female rock star) - vocals, the cast of WWRY-Russia - backing vocal, bass, additional guitar, keyboards)
We Are The Champions (from the rehearsal, October 15th 2004, features Brian and Roger). http://rapidshare.de/files/2812727/RMA.rar.html
PS: Brian's shout ''spiceba'' - means 'thank you' on Russian.
