Letraset's Magnificat by Friedrich Peter

It's not available in digital format as far as I know. More discussion can be found in this other thread.

I know that I know this, but I'm stuck on Vivaldi and Musica as names, neither of which are right, and Magnificat which I can't find.

I'm sure I can find this back at work in the morning.

EDIT: Doh! too much time looking and not enough time posting! Quick work Grant, I'd just found the old thread too.
