Here's a revised ABC, which i successfully ran thru the converter at:

(The previous version had acquired a space at the beginning of each line, and the converter had problems with that.)

Corrected lyrics (the 2 verses i sort of remember), with thanks to Felipa:

Is breathnaím amach trí na fuinneoga móra seo,
Is feicim an taoide ag tuilleadh sa trath,
Na carraigreacha loma ag lonradh faoin ngrian gheall,
Na faoileáin ina mílte .

Nuair a chloisim callán na n-inneall im' thimpeall,
'S iad ag gíoscán is ag fuaimniú is ag torann gan scith,
'Sea smaoinímse siar ar laethanta m' óige,
Ar an maidin go gleoite a d'fhág mé i m'dhiaidh.

(These are only approximate lyrics.)
