It was 40 years ago today that Sgt. Pepper taught the band to play and, although she did not perform on the album, a Surbiton housewife confirms today that she was the inspiration for one of its most famous songs.
Myth and rumour have surrounded the real-life inspiration for Lucy in the Sky with Diamonds, John Lennon's swirling ode to psychedelia.
It was first thought that the singer's muse was Lucy Richardson, a Suffolk schoogirl who went on to become a film art director.
Then speculation centred on the daughter of the comedian Peter Cook. And many believe that the song is a disguised paean to the joys of LSD. But Beatles biographers and accounts by the band members confirm that Lucy O'Donnell is the only possible source for the song.
Lucy, now a 43-year-old housewife from Surrey, was a classmate of John's son, Julian, at Heath House nursery school in Weybridge. Her moment of fame came in 1967, when Julian came home from school with a drawing of a girl surrounded by stars. John asked him what it was. "It's Lucy, in the sky with diamonds," Julian said.
