well, the only thing i noticed different about him was that in the past he never EVER cursed, and he did a few times this show. but i think it may have been because as ukranium mentioned there were some people in the crowd saying his new stuff sucks. So he kept calling them MF-ers. So lame, his old stuff IS way better. But still, it was gay.
btw, i really like scott stapp, i saw them like 5 years ago, and thought they were quite good.
