Did you ever hear the song 'Deus meus' by Na Fili on their 'A Kindly Welcome' album? That's exactly the form, with a line in Latin, the international language, and a line in the language of a particular area, in this case Irish.I think pedantically speaking that a macaronic is actually Latin mixed with another language, but has come to be applied to any two language mix.
I don't think the full lyric is given on the record sleeve notes - another piece of vinyl I can only sit and remember at the moment. The agonies of lost technology. Then again, after an unexpected storm whilst my son was on-line the other week, I can now genuinely include in a Manx phrase book,
'My modem has been struck by lightning'.
My vannaght lhiat,
