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.
I wanna know what's going on with Jericho's face in that picture ... It looks like that old animated GIF he had on his web site; the one where he morphs into a lion.
