O Sing to God (from "The Bishop's Wife")

This performance is by the Robert Mitchell Boy's Choir and is from the 1947 American film "The Bishop's Wife," starring Cary Grant, David Niven, and Loretta Young. The stills that accompany the performance are from the film.
"O Sing to God" is a Christmas anthem for soprano, alto and chorus based on Charles François Gounod's "Noël: Montez à Dieu" (1866), which was an adaptation of "Gesang der Nonnen" ("Song of the Nuns") by Johann Ludwig Uhland (1787-1862). The words are by the Rev. Benjamin Webb (1820-1885), Vicar, St. Andrew's, Wells Street, circa 1866.The English words and French music were merged in 1868 and published by Novello. Thanks to Hal Dickens for this information.
English text:
O sing to God your hymns of gladness,
Ye loving hearts your tribute pay;
Your Lord is born this happy day.
Then pierce the sky with songs of gladness,
Disperse the shades of gloom and sadness;
O sing to God your hymns of gladness.
Mark how the Mother lulls to slumber
Her new born Babe with tenderest love,
And guards her treasure from above!
O blessed Child with her who bore Thee,
We, too, will kneel in faith before Thee.
O God Incarnate, we adore Thee!
O Word of God for us incarnate,
By faith we hear Thine angels sing,
Their hymns of praise to Thee their King.
We join with them in adoration,
We pour to Thee our supplication,
That Thou wouldst grant us, Lord, salvation.
