On April 10 the Disney Parks worldwide celebrated the 50th Anniversary of the attraction “It’s a Small World After All”. Guests, cast members, and fans sang along to the music. According to an article I read Disney feels,
“The 50th anniversary of this attraction represents a celebration of the shared optimism, hope, and humanity of people throughout the world.” – See more at: http://disneylandnews.com/2014/04/10/disney-parks-celebrate-50th-anniversary-of-its-a-small-world-with-global-sing-along/#sthash.3aSMjpbE.dpuf.
