I used to teach my pupils this song (with actions!) when we were studying the Tudors. They particularly liked the verse where Anne Boleyn finds it hard to blow her nose!

I reckon children adore the macabre, within reason.

When I was a little Brownie (aged about nine) we were taught that horrible song 'Whenever you see a hearse go by..." and we just loved the bit that went:-

"Your eyes fall in and your teeth fall out,
Your brain comes trickling down your snout..."

Makes me shudder now, but unfortunately children revel in such gruesome stuff!

At Hallowe'en, the sights that arrive at our door every year make the blood run cold. Children with fake blood all over them, bolts through the neck, plastic 'fangs' and so on. Little horrors :) (literally)
