In a historic, global event, guests and cast members at Disney Parks around the world will unite in song on April 10, 2014 to celebrate the 50th anniversary of “It's a Small World."

To help announce the celebration, Disney Parks released a video last week with people around the world singing, dancing to and playing “It’s a Small World.” Filmed across six continents in more than 25 countries, the video features international “performers” – including the Mormon Tabernacle Choir, bagpipers in Scotland, Bollywood movie actors in India, and a firefighter in New York City – to create one worldwide video.

This morning Disney Parks published the full version of the Choir's performance of “It's a Small World". Watch the video above.

The video and others will be part of the launch of SmallWorld50.com, the global online hub for the attraction’s anniversary. Fans around the world are encouraged to participate online by recording on the Small World 50 website videos of themselves singing “It’s a Small World” and by creating virtual “It’s a Small World” dolls to share with their friends through social media. The dolls will benefit UNICEF (United Nations Children's Fund). UNICEF provides health care and immunizations, clean water and sanitation, nutrition, education, emergency relief and more to children around the world. $1 is donated for each doll created and ALSO for each song recorded on SmallWorld50.com.
