Who could have guessed that this Barbie doll, singing trouble-free country songs with her brother Tom in 1962 in a terminally cheerful combo called The Springfields, would become the great tragic heroine of pop music?
Forget Marianne Faithfull. Anyone can take drugs and sleep with Mick Jagger. Stifle a yawn as you rehearse the Janis Joplin story. Sex and drugs and rock'n'roll and an early death. But Dusty. Ah, Dusty. Now that would make a movie.
We start in the present day with our heroine living semi-reclusively in England's leafy Home Counties. Requests for interviews are mostly turned down. Occasionally a snapper with a telephoto lens tries to catch her going out to empty the rubbish. It's sort of Gloria Swanson in Sunset Boulevard. It wasn't Dusty that got small, it was the records.
Now flash back to the beginning, and a mystery unfolds. How did a middle- class girl born in Hampstead become one of the greatest voices in the history of soul music?
Mary Isobel Catherine Bernadette O'Brien, born in 1939 to an income tax consultant and what Dusty describes as a "pure innocent Irish Catholic" mother, somehow transcended the sub-country music that could be considered a young red-headed Irish girl's spiritual home, went solo, and, by the late Sixties, had Jerry Wexler, Aretha Franklin's producer, itching to record with her.
Dusty in Memphis, the album Wexler and Dusty recorded, was described by the New York Times as "pop music's holy grail". It is one of the most famous pop albums of all time, more heard of than heard, although the hit single it yielded, "Son of a Preacher Man", revived most recently in Pulp Fiction, never pales. The single was final confirmation not only that the girl had gone from Hampstead but that all trace of Hampstead had gone from the girl.
Dusty was always more interesting than her records, though. In the mid- Sixties, the music critic Simon Frith noted, "Dusty was the object of an oddly furtive adolescent interest. Her image, like her hair, was brittle... Her songs hinted at unspoken, desperate truths about sexuality that weren't there for discussion by little boys."
The sex thing, of course. Dusty has said she is as capable of "being swayed by a girl as a boy", and endless prurient speculation drove her from Britain in the early Seventies. She settled in California, and for a decade and a half rattled about in a big house with a big swimming- pool, drinking, taking uppers and downers, doing the American supper-club circuit, and releasing mostly unworthy records.
Until the story takes another glorious twist in 1987, when Neil Tennant, a long-time fan and smart fellow, brings Dusty home to record with the Pet Shop Boys. Miraculously, the voice is intact, "husky and breathy," says Tennant, "with an intensity and desperation that's fantastically sensual."
In the midst of Dusty's glorious late flowering, though, breast cancer is diagnosed, a blight she is determined to defeat.
If anyone can, Dusty can. In 1964 - 1964, mind you, when blonde pop stars were for amusement only - Dusty was placed under arrest in her hotel in South Africa after refusing to perform for segregated audiences. She always has had a reputation for being "difficult", arising mainly from her unerring views on what makes a good pop record.
Difficult? Sure, she's difficult. If you want simple, make a film about Kylie Minogue.
