Hi! I have only this. It's small part of "We Will Rock You" during song "Bullet The Blue Sky" on Popmart Tour 1998 from Buenos Aires.

I know, U2 bootleg called "We Will Rock You" exist. It's from Mexico City (25-11-1992), but I don't know why he called "We Will Rock You", maybe U2 performed this song during that concert.
Cheers:)
