Philboy, this song idea and lryic is much better than I expected being an earlier write by you. Please know though, your song is fine but has a couple of problems I have to mention.
First off, your verses are way to long before you get to the chorus. Then you mention in your song descpription some of the verses are spoken. That may have worked with certain songs in the 70's but not so much today. Then you mention two seperate melodies, one being "America The Beautiful" and the other being "Battle Hyme Of The Republic".
I think this idea can be very difficult to pull off; but a good producer may be able to do so. I will merely suggest this. You have studied modern country songs being played on the radio more than anyone I know. How many of the current songs attempt to use spoken lyrics or incorperate two seperate patriotic melodies in their songs, as you have tried to do with this one???
Now, patriotic songs like this are certainly out there, and there is room for one more; if it's written really well. I would suggest this would be a good song in your songwriting catalogue; but I would also suggest you go back and shorten up the verses leading up to your chorus. I like your story but I would suggest a verse and perhaps a "lift" leading into your chorus.
Just my thoughts.
