"There's a Bono factory. The band, when they saw me getting busy, opened a factory. It's just there at the back of [Dublin suburb] Tallaght. And there's various different ones, and they're being used for different occasions."
- Bono on the fact that he seems to appear everywhere and with anyone, 2009
The Unforgettable Fire album title is a reference to "The Unforgettable Fire"—an art exhibit about the atomic bombing of Hiroshima. The band saw the exhibit in November 1983 in Japan while on the War Tour.
