In the immediate aftermath of her death, Whitney Houston's name was frequently invoked alongside those of two other recently departed powerhouse female singers, Amy Winehouse and Etta James.
Amy's father, Mitch, touchingly referred to them as "a great girl group in heaven", though in reality they were all too distinctive talents for that, too demanding of the spotlight to share it. None of them would have been able to blend their voices alongside others with the modesty required to make a great vocal group, and none of us would have wanted them to hide their lights that way.
But though united in death, the circumstances of their passing differ markedly. Winehouse was taken tragically young, still in the first flush of her talent; and James was the original soul survivor, a feisty spirit who outlived the shame of America's racist Jim Crow era to make the transfer from chitlin'-circuit performer to mainstream R&B legend. As recently as last year, she faced down leukaemia and dementia to record her final album, The Dreamer. Though faltering, she managed to bring a salty panache to her performance. She may be 73, it suggested, but she was capable.
Houston was becalmed between these two extremes: her early greatness was behind her, yet she appeared not to have the determination to tough it out like Etta, herself no shrinking violet when it came to the indulgences available to stardom. For the last decade or more of her life, she was involved in one of showbusiness's more protracted crash-and-burns. For brief moments, she seemed to be steering clear of terminal impact - she would appear primped and preened on some chat-show, then hours later be snapped falling out of a nightclub bleary-eyed.
Quincy Jones, the king of black American showbiz, says he wrote Whitney a letter a few years ago, pleading with her to put the pipe aside, get clean and get her career back on track; her response, reportedly, was that she was rich enough not to care about her career any more. Which one imagines wasn't the point for Q, a man with a keen appreciation of black culture's, and black society's, need for worthy figureheads. To watch the greatest voice of her generation cast that talent aside must have been intensely frustrating.
