Before all the inevitable music star arrests, take a look at the way everything changes. When written in 1932... The Sun Has Got His Hat On went...

He's been tanning niggers out in Timbuktu
Now he's coming back to do the same for you.

I had to change it in slightly more PC 1971 to...

Negroes

Stephen Fry told me they changed the whole line for Me and My Girl in the 1980s - "He's been roasting peanuts"! Whoa!

I refused to allow Chumbawamba to change "pissing the night away" to "kissing" against fierce EMI insistence.

Times change.

The N word is probably in more lyrics now than ever before.

My brother-in -law's family's dog was called "Nword" in the sixties before anybody thought anything of it. The family were not even slightly racist and the word was usually used to describe a colour, as far as I remember.
The dog lived until he was seventeen, by which time attitudes had changed and it was difficult to get him to come back on a walk because we had to whisper his name.
