Duffy in The Sun
February 29, 2008: "That was written with Steve Booker towards the end of the recording process. I feel very lucky I met him because we wrote this song and 'Mercy
.' With 'Stepping Stone,' I had the intention to say something. It's quite personal where other songs are more about storytelling or creating scenarios. I never really use music as a way of communicating my own feelings - I do it because I enjoy music. On this occasion, I abused my authority and let my emotions in. I really love performing it live."
