O Sing, choirs of angels, Sing in exultation, Sing all that hear in heaven God's holy word. Give to our Father glory in the Highest; O come, let us adore Him, O come, let us adore Him, O come, let us adore Him, Christ the Lord. All Hail! Lord, we greet Thee, Born this happy morning, O Jesus! for evermore be Thy name adored. Word of the Father, now in flesh appearing; O come, let us adore Him, O come, let us adore Him, O come, let us adore Him, Christ the Lord.
