Many know the story: In 1814, Francis Scott Key witnessed the British bombing attack on Fort McHenry and the heroic resistance of the American defenders; seeing the US flag still flying at first light, he was inspired to write his famous lyrics. What few know is how a local ballad evolved into a national anthem and the present-day questions that surround it. In the book "O Say Can You Hear?", Mark Clague uniquely highlights the stories of the song and the nation it represents. The book examines the roots of both the lyrics and the music, alternative lyrics and translations, as well as the song's use in sporting events, during times of war, and for political protests. It shows how the song's significance reflects—and is reflected by—the United States' quest to become a more perfect Union. From a victory song to an anthem of sacrifice and an object of protest, the story of Key's song is the story of America itself.
