"Poland was probably the highlight of the tour. During New Year's Day I turned to find some water and when I looked back, the entire stadium, 80,000 people, had disappeared under a red and white Solidarity flag. I could hardly speak let alone sing. It was a really emotional moment for anyone who was there. They felt we had stood by them in that moment when they went on strike for democracy and wanted to show us they remembered."
- Bono on the Vertigo tour

In late 2004, "Mercy", an unreleased track taken from the How to Dismantle an Atomic Bomb sessions, surfaced on the Internet through a fan who had been given a copy of the album containing the extra track. The track is of less than standard audio quality, but managed to become a favorite on fan websites.
