Gordon Walker plays some slow airs and jigs. Tunes: South Uist (or South Georgia) Waling Song, Leaving Barra, An Eala Bhan (The White Swan), Rakes of Kildare, Paddy o' Rafferty, Rory McLeod, Kitchen Piper, Major Nickersons Fancy
Gordon's drones are David Naill. I don't know what reeds he is currently playing. I believe his current chanter is, surprisingly, a poly McCallum. Sadly no amount of imitating his instrument choice can imitate Gordon's fingers or his ability to set up his pipes. :)
Yes, he is indeed a Pipe Major, a distinguished graduate of the Pipe Major's course at the Castle, and one of the finest pipers who has ever been recorded.
