Whatever Eliza sings, it's Kinsale in the traditional versions of this variant.  The nonsense words may be Irish, and they may not; Eliza herself used to think that they might be Welsh.  Seamus Ennis -from whom Eliza's set may well derive- sang aber-um-vane and aber-o-ling, but he doesn't seems to have expressed an opinion as to the words' derivation or meaning.
