The Crawley performance was on an actual stage in an actual theatre so the seats were set in "circles" looking down at the stage for the most part. Kinda strange that the stage wasn't actually raised 3 feet from the ground.
Great performance though, there was a bit of trouble with the 1D stuff, but then 2D was good and a flawless 3D section which surprised alot of people, even those that knew you. A bit more work on music, tempo, theme and stage presence, and you'll be well away.
