I think this is what was wanted in the original request:

From Songs of the Hebrides, Volume 2 by Marjory Kennedy-Fraser, Kenneth MacLeod (London: Boosey & Co., 1917), page 24, which has a musical score for piano and one voice.


CUCHULLAN'S LAMENT FOR HIS SON
Cuchulann 's a Mhac.

Air and words from Duncan Maclellan, Eigg.
Collected and translated by
KENNETH MACLEOD.

Arranged by
MARJORY KENNEDY-FRASER.

ENGLISH: Woe is me! My son a-keening!
Loud o'er the moor my wail-cry,
Clanging thy shield and flame-keen sword,
Who lieth asleep in death cold.
Malisons be on thee, 'Aife,
Weaving thy pell o' hating
Thou didst wile him to his doom,
A-seeking Cuchullan of great feats
Woe is me! My son a-keening!
Lord o'er the moor my wail-cry
Cuchullan has slain Cuchullllan's son,
now lying asleep in death cold.

GAELIC: Och nan och is och eire!
Trem mi ri siubhal beinne,
Arm mo mhic 's an dara laimh
'S a sgiath 's a laimh eile
Mile mollachd air an Aife,
'Si dh'araich mi fo na geasa,
'Si chuir mise gu'm fhulang,
A dh'ionnuidh Cuchulann nan cleasa
Och nan och, is och eire!
Trom me ri siubhal beinne,
Arm mo mhic 's an dara laimh
'Sa sgiath's a laimh eile.
