Being that they are a bit younger and hipper, we tend to devote a lot of our late night time to Jimmy Fallon and Arsenio Hall. But let's not forget that sexagenarian David Letterman can still be hip and with it. To prove that, he tapped our favorite Swedish electro-pop group Little Dragon to appear on his Late Show ahead of their international mini-tour kick off. Performing new single "Klapp Klapp," the group dazzled the audience with the buzzy stunner as colorful LED lights flashed around them. While we didn't think it were possible to love this song more than we already did, the live showing elevated the song even more, showing why LD never fails to deliver quality every time they come out of the gate. If you happened to be watching one of Dave's hipper contemporaries last night, check out what Yukimi & Co. ripping the Late Show set like only they can right here.
