The following music video (Freedom for Palestine by OneWorld) was recently distributed in anticipation of the CD/iTunes release of the song. It features musicians from around the world, including Maxi Jazz (Faithless), Dave Randall (Slovo/Faithless), LSK, the Durban Gospel Choir, members of the London Community Gospel Choir, and Jamie Catto (1 Giant Leap). It has received significant attention in the past day after the video was linked to by Coldplay on their Facebook page.
