It's a common misconception that the Declaration of Independence was signed on July 4th 1776. That famous painting with our Founding Fathers gathered around the document is inaccurate. There was never a large gathering like that to sign it. After it was drawn up, it had to be ridden to several towns where the various Founding Fathers were at the time. We forget, that even when the war was over (in our perspective) there was a lot of political turmoil: What's fair and what isn't? Whose the Governor or leader of this city and so on and so forth. There was a lot to be done, and while that document is now considered to be one of the most important in our nation's history, it was actually just one of many legal documents that needed to be taken care of, and it was well into August by the time all of the signatures on the Declaration of Independence were in their places.
This song is one that I grew up listening to, the country radio stations would play it on every patriotic national holiday, not exclusively on the Fourth of July, and then of course after 9-11-01 they only played patriotic songs for what seemed the longest time. Since I no longer listen to the radio (they don't play what I enjoy listening to anyways) I haven't heard this song from start to finish in several years, and I figured it was long enough.
