But can a song stop a war? If Bob Marley and Bob Dylan couldn't do it, it can't be done.

I come from a minimum wage working world, as we all did for at least some part of our lives, and that is never out of my rearview. I've never forgotten how much your feet hurt after you've stood on them for like 12 hours.

I would like to get out to the region in the Caspian sea. I would like to go there. I would like to get to Darfur. I would like to get to Khartoum in Northern Sudan. I would like to get to Zimbabwe.
