The first song from CWB I to look at is this Christmas song for children by Pam Conn. It was in a collection called Happy Are the Children of the Lord from 1975 by Joe Dailey and Friends.
I had no luck looking for the sheet music apart from CWB I. I made up the chords for my backing.
Chorus
A light will shine on us this day,
The Lord is born for us.
The Lord is born for us.
The Lord is born for us.
1 Now arise, show your gladness, praise the Son of God.
He is life, he is mercy.
Joyfully shout to all the world,
The Lord is come.
2 Have no fears, raise your voices, sing with all your might
Of his love, of his glory.
Joyfully shout to all the world,
The Lord is come.
3 Yes, arise, look around you, his light has filled the earth.
It will shine for all generations.
We bow our heads, we lift our hearts.
The Lord has come.
