"There's this image of the 'overground'. It was a time when everyone was all indie and grey and dull—the 'underground'. The overground was like coming out into the bright light of a modern city. It's an amazing place to be, walking around these modern cities like Houston or Tokyo. And the idea was coming out into that, embracing it, going after it."
- Bono about Zooropa
Starting life as two seperate demos, 'Ultra Violet' and '69', later evolving into 'Lady With The Spinning Head', The Edge improvised a riff that the rest of the band worked with. With said riff, 'One' was born, ultimately changing the outlook of the sessions and more importantly, keeping the band together.
