Remember, remember, the 5th of November,

Gunpowder, treason and plot.

I see no reason

Why gunpowder treason

Should ever be forgot.

Guy Fawkes, Guy Fawkes, 'twas his intent

To blow up the King and the Parliament

Three score barrels of powder below

Poor old England to overthrow

By God's providence he was catch'd

With a dark lantern and burning match

Holler boys, holler boys, let the bells ring

Holler boys, holler boys

God save the King!
