While this is in David Haas’s “Table Songs” it is a communion processional by Rob Glover.
The refrain is lovely and singable, but the verses are chant style, go very high, switch from 2/2 to 3/2 and are full of tricky triplets — and so require extremely competent and talented cantors. I think the refrain could be used on its own to great effect.
The text is here (on page seven of the bulletin) and it can be heard at David Haas’s Myspace page.
