This gentle song is used at Yola’s parish. In the Catholic Worship Book, where I found a copy of the music, it is attributed to the Medical Mission Sisters, but was actually written by Miriam Therese Winter who has had a full life indeed as a sister.
The text is here. Hymnary have information on this song including the other hymnals and collections in which the sheet music can be found.
Sweet folky harmonies:
