It was good sound here in Canada!
I thought they did a great job of showing us the whole production.
Keep in mind, it's a massive venue ... and without a dress rehearsal.
Similarly, the TV cameras wouldn't have had that preview to figure out how to cover it.
Plus ... it has been a quick paced program, so in all fairness, they really don't have much of a chance to capture things, and then they're gone!
The live show was immediately followed by a re-play!! It'd kind of nice to catch parts of it again!!
The show is outstanding ... JIMHO!
