"Call and response" (and syncopation) is normal in most cultures, so far as I can tell. Given that so many Scots were involved in slave-owning situations in America and the Caribbean, it would be surprising if there were not a cultural crossover, though I wouldn't care to guess at the details.

Let's not indulge overmuch in the romantic fantasy of the Gaelic-speaking Scot as "victim"; poor people emigrated to the Americas from all over Europe because they had to. They took servants, or slaves, just as soon as they could. The Scots, Highland or Lowland, were no better or worse than everybody else.
