The video has Rita Connolly singing a Shaun Davey song at the inauguration of Michael Higgins, the ninth president of Ireland in November 2011. The words are from the early St Patrick’s Breastplate via Cecil Frances Alexander and the German linguist and Celtic philologist Kuno Meyer.
Many Irish versions exist:
CrÃost liom, CrÃost romham, CrÃost ‘mo dhiaidh,
CrÃost ionam, CrÃost fúm, CrÃost os mo chionn,
CrÃost ar mo dheis, CrÃost ar mo chlé,
CrÃost i gcroà gach aoinne smaoinÃos orm,
CrÃost i mbéal gach aoinne labhraÃos liom,
CrÃost i ngach súil a dhearcas orm,
CrÃost i ngach cluais a chluineas mé.

CrÃost liom, CrÃost romham,
CrÃost i mo dhiaidh, CrÃost istigh ionam,
CrÃost fúm, CrÃost os mo chionn,
CrÃost ar mo lámh dheas, CrÃost ar mo chlé,
CrÃost i mo lúi dom, CrÃost i mo sheasamh,
CrÃost i ngach gcrói ag cuimhneamh orm,
CrÃost i ngach mbéal, CrÃost i ngach súil,
CrÃost i ngach cluas, a éisteann liom.
——-
CrÃost liom, CrÃost romham,
CrÃost im dhiadh,
CrÃost ar mo chion-sa, agus CrÃost fúm,
CrÃost ina chónai i mo chroÃ-se,
CrÃost fós ó dheas dÃom, CrÃost ó thuaidh.
An early version of the lyrics can be found at the University of California (Davis) website. A medieval Irish version can be found on Wikisource. The second video is unfortunately unaccredited and unattributed, but has interesting photos and lyrics.
