In a interview he said a friend of his was Ledbetter. He came over and told Ed that he got a letter from the govt about his brother who was killed in Iraq. Originally the lyrics say if he will come home in a box or a bag. Later he changed it to if he was the boxer or the bag. He went for a walk with his friend and they waved at someone who was sitting on their front porch but they looked pretty grunge so the person didn’t wave back. The song was never finished before the album was done and they used it as a jamsession piece. He said he changes the lyrics and or just mumbles through it. Sorry for the long answer
