I'm looking for the lyrics to a song whose chorus is:

No matter, friends, what e'er befall
The poor folk they do work away
Through frost and snow and rain and wind
They're working life out just to keep life in

I have an old cassette tape of the Scottish band Ossian singing the song but the sound quality of the tape has deteriorated to the point of being unlistenable. Also would like to find out if the song is traditional.
