No, it's Blackstone; it's supposed to be him speaking live but is obviously pre-recorded.
He was a good enough showman that if he was speaking live he could have rolled with the punches a bit; but seeing how they obviously couldn't even have a dress rehearsal at night, setting up temporary sound-stage for a half-time show may have been a stretch.
Man that is a classic ending. Someone put a one-way mirror on backwards or something? Nothing a little arm waving won't solve. It's called misdirection!
