2008, though I liked the way he got around the vocals for 2003, and the way he sung, "It's getting harder holdin on but I can't let you go" was cool, I can't deny that 2008 it's a better all around performance.
The soundchecks served them good, in the 2003 performance it was like they just listened to the song and said, "ok everybody knows how it goes, let's play it".

I'm babbling now, sorry.
