Amy Winehouse said no when I asked her to go to rehab – the song she wrote about it turned her into a star, but five years later she was dead

Watching Amy in her early shows was like watching someone in another world. She'd hit a lyric or a melody and her eyes would roll back, her whole body would be so into it; you'd just look at her and know she was gone. The sad thing is that at that point she was only getting high from her music. Towards the end, when she got lost in the drugs and the alcohol, I never saw her perform like that again.
