Yeah, MSG was a funny one for MJ. He looks like a deer in the headlights when he first comes on stage with his brothers and takes off that space helmet. A world away from the man who owned the stage on the Dangerous/HIStory tours.
I don't think it's just being medicated, he is also clearly self-conscious and really looks like he doesn't want to be there.
It was nice to see the old MJ back on TII, the master performer, in complete control, not looking insecure or self-conscious, back to doing what he did best. Even though he never got to do an actual show, I think it was nice to see him like that one more time after the wobbly MSG shows, even if it was only rehearsal footage
But we digress....
