BBC Your Place And Mine radio interview with Martin Preshaw, by Anne Marie McAleese, on October 31, 2015.
http://bbc.in/1PXs56L Interview begins at 19:24.
"The 'pipes of the elbow' as they're called sometimes, because of the way they're played and doing that isn't easy - never mind, making a set of them, very complicated instruments. Only about 6 or 7 people in the world are real, expert pipemakers. And one of them lives in Fermanagh, near Kesh, a mile or so from Donegal. Martin Preshaw has made uilleann pipes for musicians in Russia, China, America, Canada and France - as well as here. He does it all near the house, a special place that as Helen Mark discovered, inspires him."
