Billy Joel is forty days older than me, I had exactly the same feelings he had at the time. He objected to the reasons behind The Vietnam War, and had thought about draft dodging, but he never got called. He wrote this song based on the lives of some of his soldier buddies who managed to get back home. They asked him to write it. I've never heard a modern song that more demonstrates the obscenity of war than this. For all that, it still manages to be a brilliant song in its own right. #ILikeHimHopeYouDoToo.
