So, Jack, you are saying that the Greeks, the Poles, the Balkan peoples, et al, did not have legitimate bagpipes because they were not made of African ebony? There would be an awful lot of surprised people who would lose a part of their folk culture.

While I can accept that there was also a tradition of cutting reeds and making various pipes from them, the English/Scottish/Irish pipes were not the only ones out there.

I do believe the pennywhistle is a development of those reed pipes, as is the Pan pipe.
