Sadly, Gordon took his own life in Dec 2005, his family has started a foundation to further the teaching and development of the Bagpipes in Scotland, His brother Ian is pipe major of the Atholl Highlanders, Gordon tought and inspired many many young pipers, Stuart Cassells from the red hot chilli pipers springs to mind,

astonishingly despite his world wide fame, unearthly talent and several fantastic CD releases, Gordon wasnt a professional piper, he worked as a dustman (garbage collector?) in his home town of Pitlochry.
there are several videos of him playing on "youtube" (search "Gordon Duncan") iv posted an earlier thread.

in a few weeks time there is a memorial concert in Perth featuring Dougie MacLean, Session A9, Duncan Chisholm, Ross Ainslie and Jarlath Henderson.

as well as being an amazing piper he was a fantastic composer, in my opinion the man was a genius
