Ok, I caved and watched the performance on Youtube. It wasn't as God awful as I was expecting judging by the comments. But yes, You Were was screamed through and she was out of breath through at least half of Evolution, but I was expecting way worse judging by the comments.
She just need to stop whatever it is that she is doing that is causing her to be out of breath so often these days.
On a side note, to the best of my knowledge, this is the first time she did not close this show. Arashi both opened and closed it this year.
