"Edge has just got a list of things there, one following the other. 'Don't cry, don't eat, don't drink, don't sleep.' It's kind of arcade music but at base it's a dark energy we're tapping into, like a lot of the stuff on Achtung Baby. And I use my Fat Lady voice that I used on The Fly. There's a big fat mamma in all of us." - Bono on Numb, 1993
