My understanding of the song 'world citizen', is a person who (obviously) belongs to the world. He has no country that he can call his home, and often despise certain actions of the nation he comes from. I later read that this song was written by David Sylvian as a protest to the war in Iraq.
The photo was taken with a 30' shutter speed in Ekeberg, Oslo. Just some minor adjustments in photoshop.
