"We had to build that stage in six minutes. I was on radio-controlled earphones and microphone. One error and you're off air. It was terrifying but all you can see is my usual expression when I'm terrified - a big smirk. But it was a great moment. That whole tour, we kind of fell in love with America again and they fell in love with us."
- Bono on playing the Superbowl half-time show in 2011
