LONDON — Lucy Vodden, who provided the inspiration for the Beatles' classic song "Lucy in the Sky with Diamonds," has died after a long battle with lupus. She was 46.

Her death was announced Monday by St. Thomas' Hospital in London, where she had been treated for the chronic disease for more than five years, and by her husband, Ross Vodden. Britain's Press Association said she died last Tuesday. Hospital officials said they could not confirm the day of her death.

Vodden's connection to the Beatles dates back to her early days, when she made friends with schoolmate Julian Lennon, John Lennon's son.

Julian Lennon, then 4, came home from school with a drawing one day, showed it to his father, and said it was "Lucy in the sky with diamonds."

At the time, John Lennon was gathering material for his contributions to "Sgt. Pepper's Lonely Hearts Club Band," a landmark album released to worldwide acclaim in 1967.

The elder Lennon seized on the image and developed it into what is widely regarded as a psychedelic masterpiece, replete with haunting images of "newspaper taxis" and a "girl with kaleidoscope eyes."

Rock music critics thought the song's title was a veiled reference to LSD, but John Lennon always claimed the phrase came from his son, not from a desire to spell out the initials LSD in code.

Vodden lost touch with Julian Lennon after he left the school following his parents' divorce, but they were reunited in recent years when Lennon, who lives in France, tried to help her cope with the disease.

He sent her flowers and vouchers for use at a gardening center near her home in Surrey in southeast England, and frequently sent her text messages.

Vodden enjoyed her link to the Beatles, but was not particularly fond of "Lucy in the Sky with Diamonds."

"I don't relate to the song, to that type of song," she said in June.

Vodden is the latest in a long line of people connected to the Beatles who died at a relatively young age.

The list includes John Lennon, gunned down at age 40, manager Brian Epstein, who died of a drug overdose when he was 32, and original band member Stuart Sutcliffe, who died of a brain hemorrhage at 21.
