"Yellow Submarine" was still popular years later, even after the Beatles disbanded in 1970. It appeared on television (including CBS) many times during the 1970s and 1980s, and also in small "second-run" theaters. During the 1970s, John Lennon and his wife Yoko Ono had a son together, named Sean. Sean did not know his parents were famous. One day he saw the movie on television at his babysitter's house, and came home full of questions about his father's Beatle past. Lennon told Sean that he gave up being a famous musician, so he could be a family man.
