Where does Oh say can you see by theBelong?

"Oh, say can you see" is the opening line of "The Star-Spangled Banner," the national anthem of the United States. The song was written by Francis Scott Key in 1814 and describes the sight of the American flag flying over Fort McHenry after a battle during the War of 1812. The phrase expresses a sense of patriotism and pride in the nation's resilience.
