Thousands of students across the country are learning the significance of the national anthem as part of the National Anthem Project. Yesterday, schools and communities nationwide sang the anthem to celebrate its 191st anniversary.

The National Anthem Project comes after a nationwide poll found that two out of three American adults don't know all of the words to "The Star-Spangled Banner" -- and many more don't know which song is the national anthem or why it was written.
The song includes four stanzas, but only the first usually is sung. Critics repeatedly have tried to get the nation to change the anthem because of the violence portrayed in some of the stanzas.
The campaign to reteach to the United States "The Star-Spangled Banner" began in March and is led by the National Association for Music Education, the largest arts-education association and the only one that addresses all facets of music education. First lady Laura Bush serves as honorary chairperson of the program.
