While the words to The Star Spangled Banner are both historic and inspirational, it is quite obvious from its arrangement by many singers of today that, with respect solely to the score, one might benefit from imbibing some form of alcoholic beverage before attempting to either sing it or listen to it. The music was, in fact, taken from what what was originally an English drinking song: http://www.colonialmusic.org/Resource/Anacreon.htm.
That said, I do not side with those who would change our National Anthem due to peacenik philosophies. It is simply so that I might actually enjoy singing it that I would prefer America The Beautiful, followed by God Bless America. (I think we’ll have to hurry to change our ways if we want the latter!)
