People are exaggerating, as they always do. Jon's voice is crap, but it's no worse than usual. If anything I'd say this a slight improvement over this years tour. TD sounded fine, BM sounded fine, so did Saturday Night, so did Runaway and BOR.
I don't know what everyone was expecting? For his voice to suddenly roll back to 2011 level? Not gonna happen.
Interesting to note that Jon's ditched the guitar in a bunch of songs, including Wanted, IBTFY, Runaway, Sleep etc.
Not to mention that this is the best setlist we've had in AGES. I never thought IBTFY, BOR, ITA and TD would all be played at the same show again. I think all of this negativity is unwarranted... if anything this show was an IMPROVEMENT and people are still complaining.
