“A lot of her songs were to do with Blake, which did not escape Mark’s attention. She told Mark that writing songs about him was cathartic and that ‘Back to Black’ summed up what had happened when their relationship had ended: Blake had gone back to his ex and Amy to black, or drinking and hard times. It was some of her most inspired writing because, for better or worse, she’d lived it. Mark and Amy inspired each other musically, each bringing out fresh ideas in the other. One day they decided to take a quick stroll around the neighbourhood because Amy wanted to buy Alex Clare a present. On the way back Amy began telling Mark about being with Blake, then not being with Blake and being with Alex instead. She told him about the time at my house after she’d been in hospital when everyone had been going on at her about her drinking. ‘You know they tried to make me go to rehab, and I told them, no, no, no.’ ‘That’s quite gimmicky,’ Mark replied. ‘It sounds hooky. You should go back to the studio and we should turn that into a song.’ Of course, Amy had written that line in one of her books ages ago. She’d told me before she was planning to write a song about what had happened that day, but that was the moment ‘Rehab’ came to life. Amy had also been working on a tune for the ‘hook’, but when she played it to Mark later that day it started out as a slow blues shuffle – it was like a twelve-bar blues progression. Mark suggested that she should think about doing a sixties girl-group sound, as she liked them so much. He also thought it would be fun to put in the Beatles-style E minor and A minor chords, which would give it a jangly feel. Amy was unaccustomed to this style – most of the songs she was writing were based around jazz chords – but it worked and that day she wrote ‘Rehab’ in just three hours. If you had sat Amy down with a pen and paper every day, she wouldn’t have written a song. But every now and then, something or someone turned the light on in her head and she wrote something brilliant. During that time it happened over and over again. The sessions in the studio became very intense and tiring, especially for Mark, who would sometimes work a double shift and then fall asleep. He would wake up with his head in Amy’s lap and she would be stroking his hair, as if he was a four-year-old. Mark was a few years older than Amy, but he told me he found her very motherly and kind.”

“After Frank came out, Amy would begin a performance at a gig by walking onstage, clapping and chanting, ‘Class-A drugs are for mugs. Class-A drugs are for mugs …’ She’d get the whole audience to join in until they’d all be clapping and chanting as she launched into her first number. Although Amy was smoking cannabis, she had always been totally against class-A drugs. Blake Fielder-Civil changed that. Amy first met him early in 2005 at the Good Mixer pub in Camden. None of Amy’s friends that I’ve spoken to over the years can remember exactly what led to this meeting. But after that encounter she talked about him a lot. ‘When am I going to meet him, darling?’ I asked. Amy was evasive, which was probably, I learned later, because Blake was in a relationship. Amy knew about this, so initially you could say that Amy was ‘the other woman’. And although she knew that he was seeing someone else, it was only about a month after they’d met that she had his name tattooed over her left breast. It was clear that she loved him – that they loved each other – but it was also clear that Blake had his problems. It was a stormy relationship from the start. A few weeks after they’d met, Blake told Amy that he’d finished with the other girl, and Amy, who never did anything by halves, was now fully obsessed with him.”

“The day-to-day changes in Amy amazed me: the next evening Raye called me from the studio to say that she and Mark had had a really good day working. He also said that she had been able to take her prescribed Subutex, as she had been drug-free for twelve hours. When it came time for her next dose, though, she couldn’t have it as, once again, she had taken other drugs. As a result, she went into withdrawal and the whole process started yet again. That Sunday, I drove down to the Henley studio to find Amy in bed. She was filthy and suffering the effects of withdrawal. I managed to get her into the shower, realizing again how painfully thin she was. If Amy had died at that point, I wouldn’t have been at all surprised. I put her back to bed and stayed with her until she fell asleep. Sitting in a chair next to her bed, I despaired. I was running out of ideas. If she took drugs she couldn’t take Subutex for twelve hours. If she didn’t take Subutex she went into withdrawal so she took more drugs. A horrible vicious circle.”

“I knew that Amy couldn’t have died from a drug overdose, as she had been drug-free since 2008. But although she had been so brave and had fought so hard in her recovery from alcoholism, I knew she must have lapsed once again. I thought that Amy hadn’t had a drink for three weeks. But she had actually started drinking at Dionne’s Roundhouse gig the previous Wednesday. I didn’t know that at the time. The following morning Janis, Jane, Richard Collins (Janis’s fiancé), Raye, Reg and I went to St Pancras mortuary to officially identify Amy. Alex couldn’t bring himself to go, which I fully understood. When we arrived there were loads of paps outside the court, but they were all very respectful. We were shown into a room and saw Amy behind a window. She looked very, very peaceful, as if she was just asleep, which in a way made it a lot harder. She looked lovely. There was a slight red blotchiness to her skin, which was why, at the time, I thought she might have had a seizure: she looked as she had done when she had had seizures in the past. Eventually the others left Janis and me to say goodbye to Amy by ourselves. We were with her for about fifteen minutes. We put our hands on the glass partition and spoke to her. We told her that Mummy and Daddy were with her and that we would always love her. I can’t express what it was like. It was the worst feeling in the world.”

“She had told herself she should be reassured by his squeamishness; a man who balked at scars would not give her new ones. Now she suddenly wondered if she’d had it wrong. A man without scars would always underestimate their value. He would not see them as marks of courage.”

“I went upstairs and tried to talk some sense into her but it was a waste of time. When she was high, she would babble about whatever came into her head. It was painful to watch and even worse to listen to. At one point Amy told me to cancel a proposed deal to license a perfume with her name attached to it. ‘I don’t want to hurt my credibility,’ she told me, as she sat there high on crack. ‘Hurt your credibility? What do you think smoking crack cocaine is doing to your credibility?’ It was an impossible conversation. I stormed out, with Amy shouting for me to come back. I felt as low as I’d ever been. I didn’t think Amy would die, but I just couldn’t see a way out of this. You don’t become an expert in anything overnight, and I was still learning how best to deal with an addict. Somehow or other I had to speed up the learning process.”
