A lot of people don't know all the words to the Star-Spangled Banner. What is sung is the first verse of the entire song. However, the song has 4 verses. While the first verse is good, the best verse is the fourth.
Oh, thus be it ever, when freemen shall stand. Between their loved homes and the war's desolation; Blest with vict'ry and peace, may the heav'n-rescued land Praise the Pow'r that hath made and preserved us a nation. Then conquer we must, when our cause it is just, and this be our motto: "In God is our trust!" And the star-spangled banner in triumph shall wave, O'er the land of the free, and the home of the brave.
