Came upon this fascinating thread while researching a song titled "The Seal Woman's Song" given to D.H. Lawrence in 1916 by a scholar of Celtic myth. The words are completely different and, too, seem to be vocative. From a Hebridean folk song, they are:

    Ver mi hiu - ravo na la vo -
    Ver mi hiu - ravo hovo i -
    Ver mi hiu - ravo na la vo - an catal -
    Traum - san jechar -

Could it be Gaelic? On a humorous note, British police, who suspected Lawrence to a German spy, confiscated the song, thinking that it was a coded message! Has anyone come across this version?
