This is the standard English-language version by Lachlan MacBean, as taught in schools (the DT file is taken from a record and is incomplete) and MacBean evidently considered the words to have no particular meaning and did not translate them; he did render the words into English orthography, however, in order to make the approximate pronounciation clear to the non-Gaelic speaker. I wouldn't call it a "bad" transliteration; it has served its purpose well enough over the decades, I think. Confusion only arises when people think that they ought to be hearing English words; then we get the mondegreens.
