This track is about the end of the world. On March 2, 2008, Katie Melua appeared on the BBC TV religious program The Big Questions
where she said "If The Lights Go Out" was a love song like most of her songs, and that it was about staying with the person you love until the very last moment. When questioned she added that although she didn't practice any religion she did believe in God, although she gave the impression that she was an agnostic. In an earlier interview, she said it was a song about living for the moment.
