Anyone who has been to a Disney park has heard the song, ``It's a Small World.''

The timeless Disney tune that wafts through our memories from past theme park vacations turns 50 this year.

Today Disney parks worldwide will host a global sing-along.



The Walt Disney Company will donate $150,000 to benefit UNICEF in honor of the 50th anniversary of “it’s a small world,” plus $1 for every sing-along video recorded on and another $1 for every virtual doll created on the website, up to $100,000.
