"The Star-Spangled Banner" is the United States' national anthem, written by Francis Scott Key, that is covered by The Chipmunks in the Alvin and the Chipmunks episode Baseball Heroes.
Lyrics
Opera Singer:
O! say can you
The Chipmunks:
See, by the dawn's early light
What so proudly we hailed at the twilight's last gleaming
Whose broad stripes and bright stars through the perilous night
O'er the ramparts we watched, were so gallantly streaming?
Alvin:
And the (ooo) rockets' red glare, the bombs (ooo) bursting in air
Gave proof through the night
The Chipmunks:
That our flag was still there
O! say does that star-spangled banner yet wave
O'er the land of the free and the home of the brave?
