Brantley Gilbert's song 'One Hell of an Amen' was inspired by a couple of real-life guys. One was his buddy Kory who faced up to his fatal Leukemia diagnosis by telling the doctor to, quote, "Bring it on!"

The other was a soldier named Jon who gave his life for our country. One of Brantley's friends went to Iraq on several tours. He had a best friend over there who passed away just a couple feet from where he was positioned.

Pretty moving stuff here.
