U2's half-time performance at the US Super Bowl became a moving tribute to those who lost their lives on 11 September.

The band performed Beautiful Day, MLK and Where The Streets Have No Name.

As Beautiful Day wound down and MLK opened, a giant screen scrolled the names of victims in the attacks, introducing the opening chords of Where The Streets Have No Name.

The set was in contrast to glitzy halftime shows of the past, the effects were limited to strobe lights and all attention was on Bono as he pulled back his lapel to reveal an American flag to the roars of the crowd.

Mariah Carey and Barry Manilow also performed at the event.
