Lucy O’Donnell, the girl who supposedly inspired John Lennon and Paul McCartney to write “Lucy In the Sky with Diamonds,” has died of lupus at age 46. Though the song was controversial when it debuted on Sgt. Pepper for its purported reference to LSD, Lennon’s eldest son Julian has said it was inspired by a picture he drew of O’Donnell, his nursery school classmate, in 1966. (More Beatles stories.)
