U2 in London

"I was reminded of something I had long ago forgotten - that I had written the lyrics for this song in a small village in northern Ethiopia on a scrap of paper, an Air India sick bag, I think. And there it was, nearly twenty years later, coming back to Africa, all the stuff about parched lands and deserts making sense for the first time. The hairs just stood up on the back of my neck. I could barely sing the song. And it was like that every night of the tour." - Bono on Where The Streets Have No Name during the Vertigo tour
