Months after the Sept. 11 terrorist attacks, U2 delivered a moving tribute to America and the victims of 9/11 during halftime of Super Bowl XXXVI at the Superdome in New Orleans on Feb. 3, 2002. The Irish rockers opened with “Beautiful Day,” followed by the subdued “MLK” and a powerful rendition of “Where the Streets Have No Name.” As The Edge played the hypnotic guitar part, the victims’ names scrolled to the heavens on a towering backdrop. At the end, when Bono opened his jacket to reveal a stars-and-stripes lining, the whole stadium erupted. (Bill Frakes/SI)
