I remember that song too - it's an old sea shanty:

I've never seen the likes since I was born

As a bicj buck n***** with seaboots on

Singing Johnny come down to Hilo

Poor old man.

I'll wake her,

I'll shake her

I'll wake that girl with the blue dress on

singinging Johnny come down to Hilo

Poor old man.

There are more verses, but that was the only one I knew. I cringe now to think how black people must have felt every time they heard that sung. But of course, because it didn't offend US, we never gave a thought to how it might affect others.

And remember that cute little children's song Polly Wally Doodle?

Oh I came to a river and I couldn't get across,

singing polly wally doodle all the day,

So I jumped on a n***** cos I thought he was a hoss

Singing polly wally doodle al the day.

How could anyone, ever, have have though that was OK?
