I came back here through a link from a new enquiry about this song. This thread contains Irish Gaelic lyrics which used to appear with accent marks. As with other forum contributions containing diacritical marks, the accented letters have mutated since the recent overhual of the Mudcat computer system.
  (a/) has become a German letter
‚ (e/) has become T
¡ (i/) appears as an f
¢ (o/) is now an equal sign
£ (u/) appears as a dot
