Mimixxx,
I honestly think it was a really great show. Some technical snags that seemed to put them off a bit at some points but nothing too serious. I've seen hundreds of bands live, but I don't think I've ever had the feeling that the band on stage actually cared about the fans in the room. Maybe it was because I had a good spot, but it sure felt like they were really playing for us, and not only for themselves. This might have been a less memorable night for the band, but they sure didn't disappoint. At least not me anyway.
Obvious tech snags: Curtain wouldn't go up at first, it got stuck at an angle close to the floor. And during the acoustic stage some instrument or equipment didn't work and they had to change song on a whim. Chris just went "Yeah, it's definitely f***ed", then discussed song choice briefly and just went on with it. No panic.
