Until the end of John Lennon’s life, he maintained that Lucy in the Sky was actually inspired by a painting that his three-year-old son Julian had made of Lucy O’Donnell, his classmate at Heath House nursery school.
“This is the truth: My son came home with a drawing and showed me this strange-looking woman flying around,” Lennon explained during an appearance on The Dick Cavett Show in 1971. “I said, ‘What is it?’ and he said, ‘It’s Lucy in the sky with diamonds,’ and I thought, ‘That’s beautiful.’ I immediately wrote a song about it. After the album had come out and the album had been published, someone noticed that the letters spelt out LSD and I had no idea about it. … But nobody believes me.”
