I didn't go personally, but several friends and co-workers did in STL, and said that it was a pretty sweet concert.
One guy said it was definitely better than the first time he saw them. They're his favorite band, so that might make him a little biased.
Another friend said that it was one of the longer PJ concerts that she had been to, and that she was surprised by some of the songs in the show that they usually don't play live. She also mentioned that there were two fairly long encores as opposed to the usual short one.
Hope it helps.
