With all due respect to fellow blogger Tom Van Dyke, I believe I have found a more appropriate "national anthem" for the "Christian Nation." It comes from Pastor Scott Wesley Brown (website for the song can be found by clicking here), which has the same sort or ring as Francis Scott Key!!!
Thanks to fellow blogger Brad Hart who has brought up a lot of the issues mentioned in the song. I too special note of the "changing of history" comment made in the song. Quite true, quite true!
