While at Disney, the Sherman Brothers wrote more motion-picture musical scores than any other songwriters in the history of movies. They also wrote what is perhaps their best-known song, "it's a small world (after all)" for the 1964 New York World's Fair. Since then, some have claimed that this has become the most translated and performed song on Earth, although this is largely due to the fact that it is played at Disney's theme park "it's a small world" attractions of the same name.
