Remember, remember the Fifth of November,
Gunpowder treason and plot,
I know of no reason
Why gunpowder treason
Should ever be forgot.
Guy Fawkes, Guy Fawkes, t'was his intent
To blow up king and parliament.
Three-score barrels of powder below
To prove old England's overthrow;
By God's mercy he was catched
With a dark lantern and burning match.
Holloa boys, holloa boys, let the bells ring.
Holloa boys, holloa boys, God save the King!
There's a website telling the history and explaining the practices here. Time has an article that begins:
The English, among other talents, are adept at nurturing their grudges. How else does one explain the enduring enmity toward Guy Fawkes, a conspirator in a plot to blow up Parliament in 1605? Some four centuries after Fawkes was caught, tortured and executed for his role in a scheme that never came to fruition, Britons still celebrate his demise each Nov. 5 by burning his likeness in effigy and setting fireworks ablaze.
This day features prominently in one of the Paddington Bear books.
