In the front area where we were, it was much as I had guessed. Huge floods down on the crowd so it would read in the TV cams. The 50mm I pretty much left on f2, 1/30th at 320, and the 21 I had wide open at f4 1/15th - only adjusting if I was shooting away from the lights. A 2.8 21mm would have been nice, but the added depth of field worked to my advantage in this case anyway.
Focal lengths I think worked well for the area we were in. A longer lens might have been nice on occasion - but sightlines were not such that I could have done much about what was up on stage anyway - so being limited to the crowd, this worked well.
If I'd taken a second body, or a bag, a fast 35 might have been nice, but I'm pretty happy with what I had. I rarely bothered with the XA in my pocket.
Shot UC400 at 320, and BW400CN at 320. A bit underexposed at times, but useable. The XA had Fuji 800 press in it, but I never finished that roll - I only took maybe a dozen shots with that guy. A second P would definitely have been a better choice if I'd know how little they would bother me.
