Today is the 50th Anniversary of that infectious song, It’s a Small World. For most of the world the song brings a smile to your face or an ache in your head. In celebration, this famous earworm will be simultaneously sung by choirs all over the world. On the down side of this celebration, it took us 50-years to get the song out of our head and today it will now be eternally embedded in multiple languages. Thanks a %$#@&5@ lot Disney!
