After last night’s Brit Awards, the Killers and Coldplay hustled over to the O2 Shepherds Bush Empire for a concert benefiting the international charity War Child, which released an all-covers comp featuring the likes of the Yeah Yeah Yeahs and Franz Ferdinand earlier this week. Coldplay’s first encore involved Take That member Gary Barlow coming out on stage for a cover of the British boy band’s “Back For Good,” and that was followed by Brandon Flowers—and Bono—joining that group for a rousing version of “All These Things That I’ve Done.” Apologies for the crappy video quality, but it was hard to find a clip that left the bon mot involving Steve Vai intact.
