In The film The Wall the music heard playing during the opening credits is "The Little Boy that Santa Forgot" performed by Vera Lynn. That song is about a fatherless boy. This song refers to another classic by Vera Lynn called "We'll meet again." Its lyrics include: "We'll meet again, Don't know where, don't know when, but I know we'll meet again some sunny day."
