LSB 368: Angels We Have Heard On High, Hymnary.org link

1. Angels we have heard on high,
Sweetly singing o'er the plains,
And the mountains in reply,
Echoing their joyous strains.
Refrain:
Gloria in excelsis Deo.
Gloria in excelsis Deo.

2. Shepherds, why this jubilee?
Why your joyous strains prolong?
What the gladsome tidings be
Which inspire your heav'nly song? [Refrain]

3. Come to Bethlehem and see
Him whose birth the angels sing;
Come, adore on bended knee
Christ the Lord, the newborn King. [Refrain]
