The title is a line from the Christmas song "Do You Hear What I Hear?" written by Noel Regney (lyrics) and Gloria Shayne Baker (music) as a plea for peace during the Cuban Missile Crisis (1962). The song was originally recorded by the Harry Simeone Chorale, but it was Bing Crosby's recording (1963) that was the most popular and is still played at Christmas time today (2009).
