"It was difficult. I still think it's a strong record, but we were tripped up by the wrong single. We fooled ourselves."
- Adam two years after the No Line On The Horizon release
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.
