Video: Vampire Weekend - Cousins on Conan O'Brien 1/11/10 HD 1080p

Vampire Weekend stopped by a tense Conan O'Brien set last night in Hollywood to unleash "Cousins," first single from Contra , which is available for purchase today. Fittingly, they came armed with confetti and a string quartet. No idea who provided the crew of bespectacled men hitting bells during the outro. Video after the leap. On another note: poor Conan. That dude deserves better.
