The song doesn’t specifically mention mothers, but John Lennon wrote “Julia” about his own mother, Julia Lennon, who died in 1958 when Lennon was 17 years old. Although a Beatles song, “Julia” just features Lennon singing and playing the guitar, making the song even more poignant. He sings, “Half of what I say is meaningless / But I say it just to reach you, Julia.”
