This is a Christmas song that has been added to OCP’s Breaking Bread for 2024. The new parts are by Kevin Keil, which he merges with the MUELLER version of “Away in a Manger”.
There are two vocal lines that weave about and harmonise – listen to the YouTube clip to get the idea.
The sheet music is at OCP where the text is in their preview.
My backing for learning has the vocal lines at opposite ends of the stereo spectrum for clarity.
