The site that Sorcha linked to has one more verse than the version provided by Calach.
Copied from http://www-cui.darmstadt.gmd.de/~everts/scotland.html :

Far off in sunlit places,
Sad are the Scottish faces,
Yearning to feel the kiss of sweet Scottish rain.
Where tropic skies are beaming,
Love sets the heart a-dreaming,
Longing and dreaming for the homeland again.
