Gunpowder treason and plot.
We see no reason
Why gunpowder treason
Should ever be forgot!
Guy Fawkes, guy, t'was his intent
To blow up king and parliament.
Three score barrels were laid below
To prove old England's overthrow.
By god's mercy he was catch'd
With a darkened lantern and burning match.
So, holler boys, holler boys, Let the bells ring.
Holler boys, holler boys, God save the king.
And what shall we do with him?
Burn him! (Source)
We had a bonfire here at the Abbey.
