Former UN secretary-general Kofi Annan and Archbishop Desmond Tutu joined dozens of musicians on a cover of Midnight Oil's 1987 hit "Beds Are Burning" to draw attention to the urgency of the UN Climate Change Conference this December in Copenhagen.

The remix, complete with new lyrics, was driven by one of the co-founders of the TckTckTck campaign and the Global Humanitarian Forum and wasposted today at tcktcktck.org/beds.

More than 50 musicians and celebrities collaborated on the song, including Lily Allen, Fergie, Mark Ronson, Duran Duran, The Scorpions, Bob Geldof, Marion Cotillard and Youssou N'dour.
