I was watching the end ceremony while at work and could not help but think of all that must go into making that work. Everything from running the sound system, lighting, cueing up everything etc..
I've run shows (obviously MUCH smaller) and there is a fraction of lights and sound sound channels/mics and music to worry about but it can still get pretty hectic at times, can only imagine what their systems must be like. Probably lot of people in the background making sure everything is smooth. Would actually be neat to see the behind the scenes stuff.
