Stars Tra La La Across Time on It's a Small World Ride

We all know the song – so much that it gets stuck in your head! The classic Disney Parks attraction It's a Small World celebrates its 50th anniversary this year, and we have rarely seen photos of the super famous enjoying the ride, from Maroon 5 and Donny Osmond to President Richard Nixon, Bobby Kennedy, Audrey Hepburn and the Slumdog Millionaire kids!

Check back next week as the hosts of ET sing the infamous song as part of a global sing-along; The Walt Disney Company is donating $150,000 to UNICEF (United Nations Children's Fund) as part of the celebration, and will donate an additional $1 for every sing-along video recorded by guests on SmallWorld50.com and another $1 for every virtual “it’s a small world” doll created up to $100,000 – for a total of $250,000.
