There were some moments that I was eager to see how they played out on TV, and this was definitely one of them. When I saw the overhead remote camera go in for that shot, I thought, "This is going to look amazing on the broadcast."
Re: John Legend's vocals being affected by illness...His performance of "Gethsemane" was stronger during the rehearsal, and he totally nailed the challenging notes that seemed a stretch last night. I got the sense that some of the performers were vocally exhausted by the time the end of the live broadcast rolled around (Ben Daniels is another one that comes to mind).
In defense of the audience being annoying, we were explicitly told to be high energy and treat it like a rock concert. (Although I was exchanging side-eye with the people around me when both Judas and Jesus died, because it was like, "WOOOO JOHN LEGEND YOU GO...wait. Should we be clapping here?") The sound level issues were worse at the rehearsal, with the chorus being almost inaudible at times, so I was bummed it was still an issue during the broadcast.
