Hi freqout08!. How are you?, I would like to ask you a very special favor, I'll explain what it is. There is a music group called MECANO, they did techno-pop music (they no longer exist as a group) during 1984 Nacho Cano (member) went to London city to record their songs, one of which is entitled "LA EXTRAÑA POSICION", there are 2 versions that this song: Original Version and disco-mix version, very similar one another.

In both versions you can hear a Coral singing a requiem in Latin. Nacho Cano hired the Choir of the Church of St. Matthews in London for them to sing that piece of the song. The favor I ask is that you hear LA EXTRAÑA POSICION, try to understand what's Choir is singing, write the text in Latin and Spanish translations too.
