Actually, they did AP at Barclay's and didn't at Prudential. According to the setlist, 21 songs at Barclays vs 20 at Prudential, so that was likely the difference. I agree I was also disappointed that the set was pretty much identical.
They don't typically do encores, at least not at any show I've been to. KoC is always the last song, period. At least the energy was a lot better, even if I was still surrounded by people who once again only seemed to know the popular songs and hardly anything off the current album.
Just saw the DC show got CE. Why??!! Boo!!!
