It looks and sounds like him, and he was definitely involved with that show at that point in time. I loved the New Breed when they first popped up, they used the Beastie Boys for their theme music. I even had a rat tail like Chris Champion at one point.
The Shining Wizard is a springboard (off the opponent's knee) knee strike to the temple. When Keiji Muto does it, well, when he's in the mood to put on a good show and does it, it looks pretty awesome.
