Patriotic/Military Hymns For 4th Of July Weekend Wedding

I am getting married July 1, 2006 which is the beginning of the long 4th of July weekend. My son who is in the Army will escort me down the aisle in his dress uniform. I would like the music played while our guests are being seated to be upbeat, inspirational, and patriotic. Any ideas?
