This title is taken from the compilation French Songs And Choruses For Mixed-Voice Choir (NOV165198)
Both Beata Viscera Mariae and O Magnum Mysterium (AL30765) are taken from Milhaud's 5 Prières for Voice and Organ (or Piano), Op. 231c. Arranged by Rupert Jeffcoat.
Though the Cinq Prières were originally composed for solo voice and organ, Jeffcoat has happily resisted the temptation to adapt Milhaud's short but distinctive works beyond what is necessary to transfer the music effectively to mixed voices. - Geoffrey Webber of choirandorgan.com
