I went to the U-2 concert in the Palace in Detroit on Wednesday night.
Our seats were nearly at the top of the upper bowl, but they were dead center in front of the stage, so we could still see pretty well what was going on.
I was impressed. I didn't realize before how many U-2 songs I knew. They played for maybe 2 1/2 hours (after PJ Harvey, the opening act, which I didn't care too much for—too unfamiliar I guess) and there were only 2 or 3 of the songs that I didn't know, and one of those was a cover.
