Hi,
Clément Loret between 1892 and 1895 wrote a cycle of organ pieces known under the name of "Les fêtes religieuses" (recueil de 12 fêtes de l'année liturgique). The 12 booklets were published by Frères Schott in Paris. To my knowledge the catalog of Schott Paris/Brussels has been acquired in 2007 by Schott GmbH (Mainz). Apart from the book 5 at F-Pn http://catalogue.bnf.fr/ark:/12148/cb43119944j I haven't found any records of the remaning books. Anyone has more info and or copy of the score.
Thank you
