"Scots Wha Hae" thats correct Todd, many pipers call it "Bruces address", its a nice slow tune and is many pipers first attempt at a tune, Your right it is a very old tune and I prefer to hear it on the pipes than to be sang.

Once I was at Kelso and a piper was at the foot of Wallaces staue and he played it brilliantly, he dragged the notes for ages, it was a superb bit of playing.
