Amy Winehouse's 'Back to Black' songs about her ex-husband, Blake Fielder-Civil were a "millstone around her neck" before she died.
The singer tragically passed away from accidental alcohol poisoning last year, and in the few performances she made in the year before her death she wanted to avoid her most famous material, as it was written about her ex-husband, Blake Fielder-Civil.
Amy's father, Mitch, said she suffered from stage fright, adding: "Not to an acute extent, but she needed a drink before she went on, which was a problem because the management wouldn't give her anything to drink and then there would be arguments.
"In later years, it was compounded by the fact that she felt trapped by her most famous songs. She didn't want to sing Back to Black or Love is a Losing Game because they reminded her of Fielder-Civil. She said to me many times: 'I can't do these songs any more, Dad.'
"[Those songs] were really a millstone around her neck. I can't listen to any of them."
Mitch added he received a lot of criticism for Amy going on tour — firstly in November 2007 which had to be abandoned, and again a month before her death, which was also cancelled after one disastrous show in Belgrade, Serbia — but he said doctors were supportive of her performing and touring.
He added: "Her friends used to phone me up, screaming at me: 'Why are you letting her go onstage?' But this is after me speaking to the doctors and them saying: 'It's a good thing for her to get onstage, she's got something to focus on, she's got something to look forward to.' I mean, the bottom line is that it was her choice and whatever decisions I made are irrelevant. I never made the decisions. She made them. The only decision we made was to pull the tours."
Mitch has written a book, Amy, My Daughter, all proceeds from which will go to the Amy Winehouse Foundation, a charity he set up after her death to help young people.
