It’s widely held that the Beatles’ 1967 tune “Lucy in the Sky with Diamonds” is a celebration of the wonders of LSD. But John Lennon’s son Julian says it’s about a little girl named Lucy O’Donnell who went to nursery school with him. He had painted a picture of her surrounded with stars and brought it home to show his father, who’d asked him to describe it. “It’s Lucy in the sky with diamonds,” Julian told the Beatle. “I don’t know why I called it that or why it stood out from all my other drawings,” he says now, “but I obviously had an affection for Lucy at that age. I used to show Dad everything I’d built or painted at school, and this one sparked off the idea for a song.” OK, we’ll buy “rocking horse people” as being inspired by pre-school art, but we’re guessing there’s a tab of lysergic acid diethylamide somewhere in “newspaper taxis” and “looking glass ties.” Sadly, Lucy, 46, is now seriously ill with a chronic auto-immune disease that is attacking her body’s defense system.
