This archive copy of the previously published brass and choral parts (with permission to make copies for your choir). The choral is available in either 2 pt or SATB and both are included along with parts for 2 Bb trumpets, Horn, Trombone and Tuba. This version has more accessable instrumental parts then what has most often been recorded by Canadian Brass.
