Looking at Gallus Moll's post, and hoping I've got the right J McLellan (or even MacLellan!) but 2 very good tunes are:
Lochanside - a 3/4 pipe march, and
The Bloody Fields of Flanders - the tune that was slightly adapted by Hamish Henderson to become his famous song "The Freedom Come All Ye".
Lochanside has also had words put to it by Jim Malcolm, among others.
