I dig Nelly Furtado's cover of Gnarls Barkley's "Crazy," which made the rounds a few months back. So I was psyched to find a TV performance, but it's a duet. With Charlotte Church!? Who, apparently, is now 20 and a bad-ass with a husky (!!!) chest voice, a foul mouth and her own variety show in the U.K. That, my friends, is crazy.
