They did the MGS skit but not the FF7 thing.
The Megaman medley was really cool. I looked up a video of it on Youtube and all I could find was performances in Paris and performances at the show I went to. I remembered then that they said it was the first time they had done the medley in the UK, so that was cool. They add and remove stuff all the time. Here's the one video of the medley at my show. It has more punch than the Paris orchestra (It's a different orchestra depending on where they're performing.).
Lowish sound quality but sounded great in person:
Flashing video was a bit much for my non-gaming friend I invited along, though.
