“Lucy in the Sky with Diamonds” by The Beatles

Given that it was written in the psychedelic 60s, most people think this Beatles song is about drugs, more specifically, LSD. The misconception is that the title is a way to hide the acronym LSD. John Lennon, however, swore that the title came from a painting his son Julian had made with the same title. “I swear to God or swear to Mao or to anybody you like, I had no idea it spelled LSD,” Lennon said.
