"Popmart was an opportunity to put on something vast, comical and fun. At the Las Vegas date I went out to see some of the people who were working with us. Some had aged, some were the same and for a moment I started to wonder which was the real world - the one I'd just left at home or this one? It was like a movie. As if my life at home was the dream and this was real." - The Edge
