This arangement comes from The Barra MacNeil's, Christmas Album. (note the tune is not marked in the notes, it's used to fade out track 5). The alternate name, for The New Christmas in the The Skye Collection is The Bass Reel. Lucy and Kyle (the fiddlers in the Barras) play the second half of the melody in both octaves, two fiddles doubling the melody.

This arrangement has also been published in The Silver Apple News
