AM00194. This is NOT an organ solo. It is a rescoring of the original choral accompaniment (which is basically a condensed orchestral score) into something more easily readable and accessible for organ. You may wish to acquire this if you already have choral parts from a legitimate source. Since I do not own the copyrights to the original work, I cannot offer it for free on this website. However, it is available here and here. You may also be interested in the SATB choral reduction with either organ accompaniment (available here or here) or organ and brass quartet accompaniment (available here or here) or an instrumental-only arrangement for organ and brass quartet (available here or here).
