Bono and the Edge singing

"We are not gonna top Zoo-TV. Zoo-TV is part of a multimedia thing for us, it wasn't just a moment in time, it's a much bigger thing. Our next tour will incorporate some of the bits from Zoo-TV. But I would never say that we will not go back to be four guys on a stage with acoustic guitars. I mean, I don't know we could do that. We often talked about doing an Irish record, a traditional Irish record and that wouldn't really work together with Zoo-TV. That's not out of the question." - Larry before Popmart, 1997
