This work investigates the musical structure and historical context of John Rutter's 1977 choral setting of Psalms 136 and 67. The composition serves as a technical exploration of Rutter's early stylistic development, specifically highlighting his use of harmonic language and vocal arrangement for SSA and organ. By recovering a previously lost manuscript, the publication provides a definitive reference for the performance of this specific choral piece.

Experts and choir directors identify this piece as a significant addition to the upper-voice choral repertoire. The text is noted for its technical accessibility while maintaining the distinct harmonic style characteristic of Rutter's early period.
