Drought Horses

My mum used to work with Drought Horses when young and had a real way with them, I remember her saying "woo back and "getty up boys" when we would play horses. I believe the person doing the ploughing is some relation to me as he lives in the area that my grandfather came from in Northern Ireland. And the talking is so fast at the start that I cant understand it but sounds like Ive always known it, if you understand what I mean.... Its intriguing how the horses walk in the rows so beautifully.
