Um, well I have to admit another mistake or two.

The Virginia Jubilee Ministrels were in South Africa from 1890-1898 so I meant to say that they had a tremendous influence on 19th century South African music, not the 20th century.

And I spelled "believe" wrong in that post, and maybe other words too.
I wanted to make those corrections before people started virtually tromping on me for carelessness.

[Thanks GUEST,Lighter for giving the correct meaning of "tromp".
I know you said the use of that word wasn't recommended, but some people think that anything goes on the Internet...Of,course I'm not one of them...]
