MIAMI -- Sen. Bill Nelson kicked off the National Anthem Project Road Show Wednesday at Miami City Hall -- a nation-wide tour to teach American students the "Star-Spangled Banner."

The United States' national anthem has been a source of both pride and controversy over the past two centuries. The U.S. anthem has a colorful history, starting nearly 200 years ago when it was written by a lawyer and amateur poet who added new words to a popular English pub song.

Francis Scott Key was inspired to write the lyrics after watching the bombardment of Fort McHenry in Maryland during the War of 1812.

The music had been written by John Samuel Stevens in the 1760s. He was a member of the Anacreontic Society, a British group that socialized and promoted music and poetry. The song was entitled "To Anacreon in Heaven," in honor of a Greek poet.

With the new lyrics, the song became a patriotic favorite in America for years before it was officially recognized for use by the United States Navy in 1889. In 1916, the White House acknowledged the song for official use, and Congress made it the national anthem in 1931.

Most people admit to having trouble remembering all the lyrics, and even those who do can still have trouble hitting the high notes. Over the years, there has been an ongoing debate over whether to change the music, the lyrics -- or even to adopt a new anthem altogether.

Even if you are on the short list of those who think you know all the lyrics, you might be surprised. There are actually four verses in the original version, three almost never heard. To see the complete Star Spangled Banner Lyrics click here.
