The theme song to "It's a Small World" is woven into American (and international) pop culture -- even if you've never been to a Disney theme park, you probably know the chorus. In 1964, the World's Fair came to New York, and Walt Disney and team created animatronic children of the world that featured anthems from various countries around the globe. In order to streamline the ride, which takes guests on boats through the animated panoramas, composers Robert and Richard Sherman came up with the now famous tune. Many find the "small world" experience to be a little naive and simplistic, but that's what they were going for -- people everywhere getting along so well they sing songs and hold hands. All day. For hours. The same song...over and over again.
