It may have been fun for anyone there (except for one person in the audience who Peter Capaldi caught sleeping!) but a lot of people weren't able to go. Luckily, there are a couple of people who have uploaded it.

Flicks and the City have uploaded it from one angle, where there is a reasonably clear shot of the guests with shots of the screen. Emergency Awesome has uploaded it, in two parts split at the trailer, where it simply is pointed at the big screen, so it contains everything as shown. Both are included here.
