NEW YORK -- For its last of eight shows at Madison Square Garden, U2 welcomed some very famous guests.
On Friday night, lead singer Bono gave a shout-out to former President Bill Clinton for helping to negotiate peace in the 1990s in the band's native Ireland. Bono later praised the former president and Hillary Rodham Clinton, who is running for president, for their efforts in fighting AIDS.
The Clintons sat in a tier second to the top, far from the concert stage. The Roots' Questlove also attended the U2 show and noticed the political power couple seated in the "nose nose nose bleed section":
U2 performed for more than two hours, including such favorites as "Pride (In the Name of Love)" and "Beautiful Day." For their encore they brought an old friend on stage, Bruce Springsteen, who joined them for "I Still Haven't Found What I'm Looking For" and the Ben E. King hit "Stand By Me."
During the encore, Bono once again thanked the former secretary of state for her work on promoting women and girls, but by that time, Clinton had already left.
The New York shows were part of U2's "Innocence & Experience" tour.
