Happy: Hundreds Record Videos For Disaster Fund

People from 70 countries have made their own versions of the hit Pharrell Williams' song Happy as part of a campaign to help disaster relief.

As part of the International Day of Happiness established by the United Nations in 2012, more than 1,300 homemade videos of the track were recorded featuring dancing priests, Lego figures and even computer game characters.

Fans of the song were encouraged to record their versions last month to coincide with the day on March 20.

Williams then picked some of his favourites to create a 24-hour music video on a website dedicated to raising money for the UN's Central Emergency Response Fund (CERF).

Aaron Sherinian, vice president for public relations of the UN Foundation, said: "[The campaign] showed the power of what happens when people come together around something they believe in.

"It raises awareness and funds, and has raised the level of volume of humanity in support of the UN."

More than 1,300 videos were submitted as part of the project, and fans took to social media using the #HappyDay hashtag to share photos of their efforts.

The CERF pools international contributions into a single fund so money is available to start relief work immediately after disasters.
