When the Wild Wind Blows - 2015 Remaster

This 11-minute track is one of the longest songs Iron Maiden have ever recorded. "The rhythm's a little bit different from what we've done before, and there's lots of melodies," guitarist Dave Murray told Billboard Magazine. "It's a big song. We learned it in sections just because it was such a complex arrangement, but it sounds quite natural (on the record)."

Despite the world appearing to be ending in apocalypse, the narrator has hope "now the days of our ending have begun." The song is based on author Raymond Briggs' post-nuclear fallout graphic novel When The Wind Blows.
