(Vocal Collection). With this 15-version collection, you'll always be ready to play Albert Hay Malotte's sacred classic anytime, anywhere, for anyone. The Revised Edition of this indispensable book is now even more valuable. In addition to Malotte's classic in five keys for solo voice and organ (E-flat, D-flat, C, B-flat, G), the same five keys for solo voice and piano, and a solo piano and solo organ arrangement, there are three vocal duet arrangements included soprano and alto (which could be sung by a soprano and baritone), soprano and tenor, and alto and baritone. The book is a great value; the sheet music to all these versions purchased separately would cost nearly $60!
