I'm pretty sure the screw up at the beginning of 'The Hardest Part' was Chris coming in too soon with the vocals - if they were staying true to the album version. The lyrics sounded correct to me, although after several of those overpriced beers I could be mistaken. ;)
Here are some pics I took from the pit. Wish I would have taken more, but I was too busy enjoying the awesome show these guys put on. :D
