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
And the rocket's red glare,
the bombs bursting in air
Gave proof through the night
that our flag was still there
Oh, say does that star spangled banner yet wave
o'er the land of the free
And the home of the brave?
