Having listened to both, I'm now pretty sure that your "Hebridean Lilt" is indeed "The Arran Boat Song," which has been recorded a lot.
Though never before on ocarina and pocket pipe! Very nice!
GUEST crazy, the first example of "Devon" sounds most like the "Arran Boat." Which is not to say it sounds much like it. It's modal and "Arran" is pentatonic, for one thing. The kinship lies especially in the time and contour of the tunes. They go up and down in a very similar pattern.
The resemblance of "Devon" to "The Unfortunate Rake," however, is pretty clear.
