Eyes, ears feast on U2: Show’s missteps forgivable

U2 started off its six-song encore with a mighty lemon drop – literally. Riding in the giant mirror ball, the musicians left more than a few fans wondering whether they might have a “Spinal Tap” moment and get stuck in the contraption. (They didn’t.) Rather than “Lemon” – the obvious choice – they played a slowed-down version of “Discotheque” that stripped the song of its oomph. Much better were the haunting ballads “With or Without You” and “One,” which closed the show.
