the first 3 minutes are pretty much nothing - but the magic near the end is pretty funny.
It's too bad this video ran so long. It would be way better shortened.

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.
