In 1958, John Lennon’s mother, Julia, died, and George Harrison’s mom wanted to ensure her son’s friend was OK. Though he put on a brave face in public, she overheard a conversation between Lennon and his friends in the months before his mother’s death. He said something that gave her cause for concern. Because of this, she forced Harrison to check up on Lennon. Lennon’s parents separated when he was young, and his Aunt Mimi called Social Services on his mother twice. As a result, Mimi took custody of Lennon, and he had lessened contact with her as a child. When Lennon grew older, though, he began reconnecting with his mother over music. Mimi wouldn’t let him play music in the house, but Julia encouraged him.
