The only criticism I would have about the opening ceremony is that each segment went about double what it should have. For example, the boy flying over the fields of wheat. The first 3 minutes or so were cool, but then yawn.

As for the music, in the new world Celtic segment, were any of the Ashleigh MacIsaac wannabees actually Ashleigh MacIasaac? I never heard the announcers say who the main fiddle players were. For me here in the States, this guy was the guy who first really made Celtic fiddle playing mate properly with rock/modern music. I got to hear him now and then on the radio and on CBC, because I lived in Detroit area, one of the few places where Canada is SOUTH of the USA, and close enough to pick up the cool Canadian radio stations where you could hear the Crash Test Dummies, the Northern Pikes and all way before they got popular in the US.
