Bono: You have Luciano Pavarotti, the greatest singer on earth, maybe who ever existed, calling you at home trying to get us to write a song. Nicoletta Mantovani: He called Bono for ages. He became friend of the housekeeper of Bono, because, she was Italian. Bono: Our housekeeper, Theresa, he just got to know her. He'd ring and say, "Is God at home?" The technique was one of humility, which is, of course, a very mischievous trick. He had turned our housekeeper into his Consigliere. Because at breakfast, dinner and tea, she was like, "Have you got that song done for him?" Nicoletta Mantovani: Bono said, "I don't have a song. I have no idea." And Luciano said, "God will inspire you." Bono: I remember this Easter coming up and he said, "Ah, God will sing him something." And, I woke up with the melody. And it really did happen - like that.
