'I think I completely lost myself at various points and became an utter madman. That US festival thing. I climbed to the very top of the stage, it was like hundreds of feet up, and walked across the top of it on the canvas, and the canvas ripped. God! I can't watch that! I don't know who that person is. I don't know who it is climbing up there. I'm afraid of heights anyway.'
Bono, January 1985
