• Duffy in The Sun February 29, 2008: "That song is about losing somebody but not necessarily in a relationship. It's really about death, the cold silence that goes along with it and that feeling of fear when somebody suddenly disappears out of someone's life. I just wanted to create that atmosphere. I can't say that I've lost somebody that I've lived with so I didn't perhaps sing it from a personal perspective."
• Duffy added in the same Sun interview: "I didn't want to make an album with every single song sounding the same. I remember Bernard (Butler) and Jimmy (Hogarth) probably thinking I was a lunatic, you know, because they were like 'What are you looking for?' We'd do one song and then I'd try and move as far away from that as possible. That's why I think you just get this real mix of emotions, of light and shade."
