Bono invited The Killers' Brandon Flowers on stage this weekend during U2's performance in Las Vegas for a cozy, little duet. Hot! Before they sang "In A Little While," Bono introduced the guest singer by telling the audience he had some vocals problems and needed help from the singer from the "swankiest rock and roll band on the planet." I told ya that a year and half ago.
U2.com adds some detail: "And then another great twist, a full version of In A Little While, a song that has appeared in little snatches here and there but tonight comes complete with Brandon Flowers from The Killers. Amazing to think that Brandon came to see U2 in this venue less than five years ago on the Elevation tour, when he was still waiting tables, scoring a ticket off a tout - and was totally blown away by the show. And now he's a rock'n'roll star too, taking his band on the road with U2 and tonight, in his hometown, with his new wife in the audience, getting up on stage with U2 to sing with them. It really was only a little while for Brandon to become a star." [Source]
