I know Stevie is a big supporter of our troops. I saw FM in concert, and Lindsey Buckingham said before the song 'Peacekeeper'; "Without justice, there is always force." Read into that all you will.
Singer Chris Isaak should be added to the list. He's been overseas a few times to perform for our troops in Afghanistan.
Sheryl Crow performed for our troops in Bosnia. I remain suspicious of FM. :)
