On another tangent I actually decided to check out the first episode of Ikemen Desu Ne and so far I enjoy it. I'm a fan of the more lighthearted dramas and while I won't say it's amazing it's still good fun fluff. I was surprised to see the members of They Budou in it and unfortunately I'm not familiar enough with the older back dancing groups to recognize if M.A.D. or M.A.D.E. were the other back dancers shown in the drama. But if you're a fan of They Budou I would recommend watching if only for the locker room scene.
