This must have been amazing to witness. Unfortunately, the video document is not stellar in quality, but you get the idea. War Child's 15th anniversary concert, and Coldplay is joined by Bono and The Killers' Brandon Flowers for his band's "All These Things I've Done." Now, this song is probably my top karaoke choice of the moment and gotta say, Bono, I rock the cadence a little bit better than you do here. But he's probably not belting it out every Thursday in the East Village, so I'll give him that.
