This is the Mormon Tabernacle Choir's Rendition
(Thanks to my wife whose ears are better than mine).

Upon this Holy night,
A rush of birds in flight
Their voices filled with splendor.

-Came birds in joyful throng
To sing their praise in song
With carols soft and tender.

-All sang unto the child
To Mary sweet and mild
In adoration tender.

The kindly eagle came
To praise his Holy name
The nightingale came flying.

-All circled and replied
"Tonight is Christmas Night"
Their songs of love were crying.

-The cuckoo and the quail
Flew over hill and dale
They sang of love undying.

Upon this Holy night
Upon this Holy night
Upon this night...
This night a rush of birds in flight.
