Being May I suppose I have to go back to Gather Australia and plough through their Marian Hymns.
This is a canon in four parts. The Latin text is here. Cantus Mundi have the melody line and English text.
My backing has the melody line and then the secondary line comes in the second time around. I don’t attempt the canon.
This is the canon and secondary canon going bananas:
Very Nice Hymn.
Bless to hear this one.
God bless you.
