Jukka Ammondt is a Finnish professor of literature who has translated some Elvis Presley songs into Latin. This BBC post from 2006 gives some examples, including “Cor Ligneum”. Is “Es Solus Canis Venaticus” is part of his repertoire? Do the Latin translations scan as well as the original lyrics?
It isn’t only modern music, either originally or in translation, that seems to feature Latin, but also cashpoint instructions in the Vatican City.
