Please, PLEASE read one of the threads about Siul e ruin, eg origins thread and listen to this most beautiful of songs,

eg: Clannad : Siuil a Ruin

You will see and hear that the PPM song is based on an Irish song and the original Irish language refrain has been changed by those who didn't understand it into something they could sing... but the original words are FAR from being nonsense.

(I feel better now!)
