"Playing Croke Park in 1985 was probably the high point of the Unforgettable Fire tour, because we really had done it. This wasn't a band that was doing OK, this was a band that was topping the charts and had broke America and the world, coming back to play in their home town, in the centre of their city."

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.
