This is a St Louis Jesuit song that passed me by, but was used at RS’s parish over Easter.
This is a major production by Bob Dufford SJ with seven verses that have markedly different tunes so the assembly just gets the refrain. He has based the text on John 14-16 and 1 Corinthians 13.
While my backing has the lot, just to see how far he can stray from the original key, it is not intended to by played in its entirety:
Some common combinations are: Ordinary Time – verses 1,2,4,6 … Holy Thursday – verses 1,2,4,6; Social Justice – verses 2,7,6; Weddings – verse 3,5,6.
That covers some territory.
The song can be purchased at OCP where the text in the preview.
