The Glover family is cleaning the kitchen together when Big Bill mentions to Brenda that "their song" is playing on the radio and asks her to dance. April takes the hint that her parents might like to be alone together and tries to escort her brothers out, but Little Bill doesn't understand when April says they'd like some "private time." Brenda explains that it means sometimes people need to be alone with someone to talk, or just spend time together. Little Bill is still a little confused, and says that his walks on errands with his mother must be their private time, so his parents decide to just explain it to him when he's older. Alice the Great is entertaining an old friend, Jazz musician Clark Terry, but Little Bill is feeling a little put out because Sunday afternoons are usually the time he spends with Alice by himself-- it's their "private time." Alice invites Clark to join them on their walk to the park, but they go to a different area than they usually do. Little Bill points out that they are doing things that they've never done before, like see a new pond and learn to play grass blades, so Mr. Terry improvises singing the "Never" song for Little Bill. At school the next day, Bill tells all his friends about Mr. Terry, and he sings for them the new songs he made up. He invites his friends back to his house to sing with Clark after school.
