Say what you will, school dinners make you ill,
And Davy Crockett died of shepherd's pie,
All school din-dins come from pig bins,
Why, O why?

Last line was
Out of Town not Why, O why
In the version I knew at the school in Folkestone

Say what you will, school dinners make you ill,
And Davy Crockett died of shepherd's pie,
All school din-dins come from pig bins,
Out of Town
