Bono and Edge busking in Dublin on Christmas eve

"I actually want to make quite a personal record. I tried to avoid any persona on the record. The song MOFO was first called The Return Of The Fly, like a B-movie and then it became the heaviest song maybe we ever written, I feel like my whole life is in that one tune. After work I might have developed a few personas." - Bono on Pop, 1997
