Uh Bob, I hate to burst your bubble but there is no "as written" tune.

In 1814, Francis Scott Key wrote new words for a well-known drinking song, "To Anacreon in Heaven," to celebrate America's recent victory over the British. However, only in 1931, following a twenty-year effort during which more than forty bills and joint resolutions were introduced in Congress, was a law finally signed proclaiming "The Star Spangled Banner" to be the national anthem of the United States.

On Sept. 13, 1814, Francis Scott Key visited the British fleet in Chesapeake Bay to secure the release of Dr. William Beanes, who had been captured after the burning of Washington, DC. The release was secured, but Key was detained on ship overnight during the shelling of Fort McHenry, one of the forts defending Baltimore. In the morning, he was so delighted to see the American flag still flying over the fort that he began a poem to commemorate the occasion. First published under the title “Defense of Fort M'Henry,” the poem soon attained wide popularity as sung to the tune “To Anacreon in Heaven.” The origin of this tune is obscure, but it may have been written by John Stafford Smith, a British composer born in 1750. “The Star-Spangled Banner” was officially made the national anthem by Congress in 1931, although it already had been adopted as such by the army and the navy.
