I just listened to a group people singing shape notes from a book called the church hymnal published in about 1951 and never reprinted. I have been searchin for it but haven;t located a copy
This is most likely "Church Hymnal" (CH1951) published in 1951 by Tennessee Music and Printing Co. for the (Original) Church of God
…is Pathway Press. An internet search with the hymnal and publisher names will yield links for purchase. About $11.
