I was a fluent and avid reader by the time I started Junior School at the age of seven.
It must have been pure mischief therefore which made me persuade my classmates that there was no such thing as a "pilgrim" and that the word on the hymn sheet (a big flip chart thing on an easel at the front of the Hall) was meant to be "Penguin"
So the whole class sang:-
"There's no discouragement, will make him once relent,
His first avowed intent, to be a penguin"

At a later school, I remember a very un-PC song
"Sally Brown, she's a bright Mulatto,
Way hey Roll and go!
She drinks rum and chews tobacco
Spend my money on Sally Brown."
Cheers
