Well, I found another longer note telling the tale how that song came into life. If you click on the link you also will find easily a midi that is nicer to listen to than the Mudcat midi and you will find a link to the American song "Ellie Rhee" or "carry me back to Tennessee". Sarie Marais has been written to the tune of Ellie Rhee. Ellie Rhee has been written by Septimus Winner. So the tune to the traditional Africaans folksong Sarie Marais has been written by an American, the same man who wrote Ten little indians. Funny connection.
