Ryan put up his parish music selections last week and they included this song. It is Omer Westendorf’s translation of Ubi Caritas, set to a tune called CHRISTIAN LOVE by Paul Benoit OSB.
The text is here and the sheet music is available at WLP in C which is probably too high unless you have an accomplished choir.
I’m guessing the chords here and I don’t fully understand what time signature is happening here but this is my backing in G.
