David Guetta
A video by DJ David Guetta screened onto the UN skyscraper in New York last 23 November launched a campaign to raise cash for disaster victims of the Philippines typhoon and Syria war.

The blacked out UN headquarters provided the backdrop for the screening of the "One Voice" single by Frenchman Guetta and singer Mikky Ekko.

Guetta, renowned in nightclubs the world over for songs such as "Just A Little More Love" and "Sexy Bitch", said he was moved by the Syria conflict and the November 8 Philippines super typhoon to launch The World Needs More campaign.

The DJ and corporate giants will pay out cash to the UN humanitarian agency when the hashtag #theworldneedsmore and other words are Tweeted.

Guetta is sponsoring the word "love" so that every time someone uses the hashtags #theworldneedsmore #love, he donates $1. Major banks and enterprises are sponsoring words like "dreams," "strength" and "dialogue."

"Together we can use our voices to make a real difference for people in need around the world," said Guetta at the screening with UN leader Ban Ki-moon.

Ban said that Guetta is "an example of true humanism and solidarity" but that the music star also deserves a prize for optimism. "This is the man who thought he could teach me to dance," Ban joked.
