CLIMATE CHANGE

On October 2 2009, 60 musicians and celebrities from around the world released a free reworked version to highlight climate change issues ahead of the United Nation's talks in Copenhagen. Singers included Lily Allen, Simon Le Bon from the '80s group Duran Duran and Bob Geldof. The former UN secretary-general Kofi Annan, Archbishop Desmond Tutu and French actress Marion Cotillard also added their voices to the cover version. The song is part of Global Humanitarian Forum tck tck tck time for climate justice campaign and is a part of the greater "TckTckTck" project[3], which aims to draw attention to the urgency of the global warming crisis, by signing a "musical petition" with each download.
