Interesting question. With so many Scots travelling to the New World you would think there would have been a greater tradition. I have the set of Border pipes my gr.gr. grandfather brought to Canada in 1833. He was first a millright and then farmer. There were many Scots in the surrounding farm region in central Ontario, and so he had a regular audience of rural folk who apparently would travel from miles around by horse and buggy to hear him play his in his orchard in the evenings. These are bellows-blown 'cauld wind' pipes, but they also have a mouth pipe. They were passed to my father, who was the last player.
