U2 in Rome

"The job of rock'n roll is to blow people's heads. Everyone else is into nostalgia. It's really peculiar to me that at the far end of the 20th century you have all this obsession with the sixties. Let's do something that's forward looking and fresh. That's why we came up with this, what we had in our minds was to make a big sci-fi gospel show. We wanted Martin Luther King in the building, along with Elvis and anyone else we could find." - Bono on Popmart, 1997
