Disney is to mark 50 years of the It's a Small World theme park attraction with a worldwide sing-along event.
On April 10th, a live sing-along will be held at Disneyland and Disney World, and will be paired with sing-alongs recorded earlier in the day from other Disney parks.
The event will air on Good Morning America along with others singing snippets of the song.
The website www.SmallWorld50.com has been launched and invites members of the public to submit videos of themselves singing the song.
The site also allows fans to create virtual dolls, mixing and matching faces, clothes and other elements to build a unique figure.
The original 1966 attraction was billed as 'a salute to UNICEF and all the world's children' so to mark the anniversary, Disney is donating $150,000 to UNICEF.
Disney will also donate another $1 for each video and doll posted or shared on SmallWorld50.com or related social media, up to $100,000.
