"Bono volunteered me to be photographed naked, as I recall. I was still a young man and the idea of doing a nude photo shoot appealed to me because I'd been looking at Robert Mapplethorpe's work and following that whole New York photographic art scene. I knew there might be repercussions but this was a one-shot opportunity for me. This was the right record for such an expression." - Adam on being photographed naked for the Achtung Baby album
