the album's success led to a period of confusion about her role in the music business that nearly led her to quit music. duffy has said that she did not mind people illegally downloading her music because she believes most people who do are kids who cannot afford the cds and will buy them when they get older. duffy recorded a cover of paul mccartney and wings' song "live and let die". it was used on the war child charity album titled "war child heroes, volume i". acclaim came from paul mccartney, saying that duffy's version "is great – i was really impressed". duffy and bernard butler wrote the song "smoke without fire", which appeared on the soundtrack for the film "an education".
