This might be a long shot as I don't know how well-circulated this Mass setting was...I'm looking for a score of the Mass of the Holy Rosary by Rev. R.J. Sorin which has an organ accompaniment. I currently have an arrangement of it for three voices, but the organ accompaniment is very sparse as it's basically just the voice parts. I'm hoping there might be a more substantial accompaniment available, but can't find anything online except for a MuseScore arrangement with an accompaniment for strings which will be a bit time-consuming to typeset for organ.

Any help appreciated!
