This is yet another lovely piece from John Bell and Wild Goose that was included in Gather Australia.
Wild Goose has this information about the song including the note that the first line is “Jesus Christ, Lord of all, stay with us now.”
That is all the refrain for the assembly consists of, and the cantor has ten one line exhortations that are sung over the “now”.
The sheet music is also in the collection Love From Below available at Wild Goose.
My backing is just the assembly part and I had to make up the chords.
