Amy Winehouse's taxi driver father, Mitch, spoke to the BBC about an extramarital affair that he had with a work colleague, Jane, which carried on for almost a decade before he eventually left his family to move in with her. It was an open secret in the family home and Amy and her older brother Alex even had a special name for their father's mistress: 'Daddy's work wife.' After his daughter wrote this song, the taxi driver realized that the line in this song "All the s--t my mother went through" referred to his affair. Mitch said: "The children used to call Jane 'Daddy's work wife.' I did not leave home until Amy was ten, so the situation occurred for another eight or nine years before I left home. It was difficult. I should have left earlier, I should have left sooner. There was not really a negative response from Amy (when I left), but she definitely became a lot more independent. Perhaps deep down she felt her parents were splitting up, she could not rely on them to stay together and that it was about time she learned to look after herself. I thought Amy was over it pretty quickly - in fact it felt at the time Amy felt no effect at all. Maybe she could not articulate it in words, but she certainly did it with music."
