The title of the song is inspired by Maiden singer Bruce Dickinson's words during their performance of "The Trooper
" during what is called "the Ozzfest incident" among fans. Despite their set and equipment being sabotaged during the festival in Florida, Iron Maiden continued to perform. Typically, Dickinson waves a British flag during the song. At this performance, a saboteur was on stage waving an American flag. This caused Dickinson to comment, "This is a British flag, and these colours don't f--king run." On the DVD for A Matter of Life and Death
, Dickinson confirmed that the phrase refers to the colors on the British flag.
