Musicians from across the world combined to make this video - makes you wonder why there is so much bloodshed in this world and so much imposition of one person's will on others.  True freedom means there would be none of that.  The caption on Vimeo is the following:

"This video was created through a partnership between PFC and the United Nations Millenium Development Goals Achievement Fund. We realize that true change for the good of everyone always comes from the hearts of the people, and with music we can unite together to make the world A Better Place."
