Lennox wrote: "Amy Winehouse had a massive gift. I watched her performing live in a little place in London when she was just 18 years old, and she blew everyone's socks off.
"I felt, and still feel deeply outraged and upset to think that anyone could have even considered that she was fit to go on stage only a short while ago, never mind go on tour, when she was clearly in such a desperate state, and so badly needed healing."
Lennox also had strong words for the press, adding: "I hated that she became such tragic tabloid fodder. There's absolutely nothing "mythylogically" (sic) attractive, heroic or interesting about drug and alcohol addiction. Nothing whatsoever. It's just terrible... full stop.
"Now I expect there'll be a feeding frenzy, and of course, her recordings will all soar up the charts. She was amazingly talented… and it should never have ended like this."
