Question: Rare Coldplay/U2 Duet? I stumbled across "What's Going On" on limewire and I want to know if it's real, and any other information on it, because I think if Coldplay and U2 would have recorded a song together, I would have heard more about it.

Answer: They did another song together i think a while ago, i forgot which song it is, i know its U2's though, and Bono also sang a snipet of yellow at his concert by coldplay, u can find it in the coldplaying forum heres a link
