Dunno the name of the tune but at school we learnt

Mr Rabbit Mr Rabbit
Your ears are mighty long
Yes my Lord, they're put on wrong
Every little soul must shine, shine, shine
Every little soul must shine (clap) shine, shine.

On the bawdy side there's always (to the tune of Frere Jacque)

I like spanking, I like spanking
Spanking nuns, spanking nuns
I like spanking dead nuns, I like spanking dead nuns
Dead nuns' bums, dead nuns' bums.

Traditional

Hey ho nobody at home
Meat nor ale nor money have I none
Yet will I be merry
