I've got to say, I love these guys.  And, what the hell, why not make a play for better relations between Japan and South Korea with their motto (you'll see it at the very end):

Oh, and somehow I missed this next one, which came out last year (guess I got behind in following my favorite Japanese-MMA-turned-popstar videos…):

And yet a third one, "Aquarius," which is not quite as snappy but has some good moves, can be found here.  Great stuff.
