Will - Don't want to seem a pedantic old sod but in my copy of Ian Burns's book (that he kindly signed for me) Spootiskerry is the only spelling shown. Though he does mention an earlier spelling Spootskerry but always as one word. Damn good tune anyway and one I remember took no time to learn. Incidentally it can all be played on the black notes of the piano apart from one passing note in the second part.
