'American Idol': Kris Allen, Adam Lambert and Allison Iraheta go 'Crazy'

adam-kris-allison-video-320.jpgAll the Adam Lambert fans who bailed out midway through "American Idol" triple-bill concert in New York missed one heck of a show closer.

Lambert, Kris Allen and Allison Iraheta played "Idol" host Ryan Seacrest's "Rock My Town" show at Manhattan's Highline Ballroom Friday night (Feb. 12). The three season 8 finalists played sets in the order they finished, with Iraheta kicking things off, Lambert rolling through an 11-song set in the middle and Allen closing with a set that included "Heartless" and "Falling Slowly" (mashed up a little with U2's "With or Without You").

MTV News reports that a contingent of Lambert fans left after his set, which means they missed not just Allen's set but a closing number that brought all three performers to the stage. The trio -- which Allen dubbed "Kradison" -- ripped through a cover Gnarls Barkley's "Crazy." Several fans captured the performance on their phones, though, which means we can share it with you. Have a look.



Pretty hot, right?
