Katie Melua told I Like Music: '"If The Lights Go Out' is a love song saying that 'I'll be with you until the last moment.' Some people think it's an anti global warming message song, which it isn't at all. It's just trying to be a bit hopeful and also trying to talk about being in love and getting priorities right."

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. >>
