"U2 has been on the verge of irrelevance for 20 years. We've ducked and dived and dodged it."
- Bono, 2011
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.
