A star-spangled quiz in honor of National Anthem Day

Oh, say did you know? Friday is National Anthem Day in the United States.

It's more than 200 years old, but "The Star-Spangled Banner" wasn't always the song of America.

In fact, it wasn't even originally named after the stars and stripes. When Francis Scott Key wrote it in 1814, he titled it "The Defence of Fort M'Henry."

That's because he had been inspired by the sight of Old Glory flying over the Baltimore fort after a night of heavy British bombardment during the War of 1812.

But Key, who had set the text to the popular English melody "To Anacreon in Heaven," later renamed the tune "The Star-Spangled Banner." (Go see it: The actual star-spangled banner that inspired the anthem is on display at the National Museum of American History in Washington, D.C.)

The full song contains four verses, but the last three are generally omitted in performances.

Beloved during the 19th century, the tune "gained special significance during the Civil War, a time when many Americans turned to music to express their feelings for the flag and the ideals and values it represented," according to the Smithsonian.

"By the 1890s, the military had adopted the song for ceremonial purposes, requiring it to be played at the raising and lowering of the colors. In 1917, both the army and the navy designated the song the 'national anthem' for ceremonial purposes."

However, it did not become America's official national anthem until March 3, 1931 (hence, National Anthem Day).

Today, the song is regularly performed at patriotic occasions and sporting events, and everyone from Whitney Houston to Lady Gaga to even Roseanne Barr has tackled the song.

But though it's well known, plenty have flubbed — or even plain forgotten — the lyrics, including Christina Aguilera, Michael Bolton and James Taylor.

What about you? How well do you know the lyrics?
