`Great big rock band’: U2 steals own show this time

Though U2 has been making records for almost two decades, the musicians opted to concentrate on the new rather than indulge in nostalgia. But that’s not to say that they didn’t have fun with a few oldies. While their set list included nine cuts from their current “Pop” album, one of the evening’s highlights was the Edge’s campy solo turn at singing “Sweet Caroline,” karaoke style. The guitarist appeared to be having a great time, punching his fist in the air and encouraging fans to sing louder.
