At long last, here is the video of Grand Master H doing his musical number in June.
He is the tall one with the crew cut (his choice). He did NOT want to wear his costume because it had fake dirt on it. Apparently he has pretty strong artistic vision and it did NOT mesh with what he was being offered.
As you can see, he is extremely committed and serious. I wish to hell he would at least smile a little bit during one of these shows!
