Here is a song titled Young MacDonald that I'm about to add to my Canadian tunebook.

Though the song is about a young chap in Glengarry County, Ontario, Canada, it's origin is obviously Gaelic. My question is: Are the snippets of Gaelic text in the lyrics real or just phonetic mush? Do they translate into anything that makes sense?

Does anyone recognize the tune from which this originates?
