Choral Choir (SSA) - Level 2 - Digital Download SKU: A0.935697 Composed by John Tams. Arranged by Rebecca Ferrari. Contemporary. Octavo. 9 pages. Rebecca Ferrari #5319493. Published by Rebecca Ferrari (A0.935697). A beautiful duet for two lower alto voices with SSA chorus. I heard the original song at a mesmerising production of the York Mystery Plays, in the scene depicting the birth of Christ. Because of that, I have always heard it as a devotional song, a prayer for strength and sanctuary.
