Well, just tell Lucius that Mozart didn't really write the version of the Requiem that exists today- he died before it was out of skeletal form. We have his student, Herr Sussmayer, to thank for the slightly lopsided (but still wonderful) mass. If Lucius wants a Requiem with proper pedigree that lacks all the Catholic "reqiuem aeternam" nonsense and even shows proper respect for family, hook him up with the Brahms German Requiem! Biased? Moi? :D
