Honestly, when I think back to my childhood (millions of years ago!) the songs we sang at school and in the Church, Brownies, Girl Guides etc would make ones hair stand on end nowadays.

"Over the sea there are little brown children,
Fathers and mothers and babies dear.
They have not heard of our Father in heaven,
No-one has told them that God is near..." (sung in Sunday school, missionary song)

"Land of the silver birch, home of the beaver..." ('Red Indians' song)

Ching ching Chinaman chop chop chop.
Me aflaid all the tlade velly velly bad.
No joke, stoney bloke,
Gotta shut the shop.
Ching ching Chinaman chop chop chop."

How embarrassing eh?
