The family of Amy Winehouse was forced to employ security men to stop drug-dealers secretly supplying her with crack cocaine while she was being treated in a rehab clinic. And the singer’s father, Mitch, has revealed he can’t bear to listen to Winehouse’s hit album Back To Black as most of its songs are about his hated former son-in-law, Blake Fielder-Civil. In his new book, Amy, My Daughter, Mitch reveals the singer was furious when guards foiled a plot to smuggle drugs hidden in a bunch of flowers and a teddy bear into the hospital where she was recovering in 2008. One of the dealers was a friend of Winehouse’s then husband Fielder-Civil who introduced her to heroin and cocaine and who, at the time, was in prison for an assault on a bar owner. Winehouse, who died last July aged 27, reluctantly agreed to be admitted to the Capio Nightingale, a psychiatric hospital in West London, after her record label threatened to stop her performing unless she came off drugs. Her father writes: “Amy had an incredible power of recovery, given the quantity of poisonous substances involved. I had a call from the hospital to say one of Blake’s friends had smuggled drugs in, crudely stuffed inside a teddy bear.” Mitch said the smuggling operation continued even after the singer suffered a seizure and had been transferred to another hospital. “We had security to look after her by this time and the next day I took a call to warn me a package was on its way. I jumped in my cab and reached the clinic just in time to see a known drug-dealer with some flowers for Amy. Security searched it and found a rock of crack cocaine. Amy went mad when she found out we’d intercepted the drug.” Winehouse’s father, 60, said he and his wife, Janis, were heartbroken when Amy married Fielder-Civil in secret in 2007. He said it was difficult for him to listen to the chart topping Back To Black album because most of the songs are about his former son-in-law. “I don’t like it as much as her first album, Frank. And that’s for one reason only: all the songs, apart from Rehab, are about Blake. It occurred to me that one of the biggest-selling albums of the 21st Century is all about the biggest low-life scumbag God ever put breath into. Quite ironic, isn’t it? “Amy’s passing was, and is, unbearable. Our lives have changed for ever and will never be the same again.”
