World Series 2013 In Boston, ‘God Bless America.’ Sung By Marine [VIDEO]

This video of the great song 'God Bless America' is just going viral and I just saw it on Facebook. 'God Bless America' and our National Anthem bring tears to my eye every time. Retired United States Marine Sgt. Dan Clark sends his version of 'God Bless America' out of the ball park. Just listening to him sing makes me proud that I am a United States American! Semper FI!
