On today's SBS Inkigayo Vancouver Olympics Special boy groups BEAST and 2AM hooked up on stage to perform a kpop classic, Psy's Champion. The two groups did an excellent job of bringing back this track with the original fun flair that Psy gave it. Though they're a ballad group, 2AM definitely knows how to have fun and bust a move in a genre that's definitely not their own. BEAST is the go-to newbie group that fans can count on to make 'em smile with their dorkiness on stage. The original track was a very upbeat song and it was definitely the perfect song for these boys to perform. Check out the original and the new version below. http://www.youtube.com/watch?v=DTT9MT0rMhU http://www.youtube.com/watch?v=jmJpNRzYTc0
