In her kind response to my quandary over singing the Celtic Alleluia, Josie pointed out that some parishes use a chant response.
Chris has come to the party with his chant responses and other suggestions:
Attached are written out verses for Ordinary Time Year A using Psalm Tone 8 (from my LiturgyShare.org website). For obvious copyright reasons the Celtic Alleluia is not included, but the verses have been laid out in a manner that allows the page to be folded or cut in half to fit underneath a legitimate copy of the Alleluia. If there’s any interest in this I can do the same for the other times in the liturgical calendar as they are already written out for my own Alleluias.
Some other sources of verse tones:
Catholic Worship Book II: hymn 48 (accompaniment edition) has a verse tone from A. Gregory Murray, OSB. You have to write out the words yourself, but that’s simple enough, and you can use mine as a starting point.
Gather Comprehensive, 2nd ed., (choir/accompaniment edition): hymn 266 with fully written out verses for Ordinary Time by Marty Haugen (of all people!). I don’t have the current edition to know if they are still included. Verse texts are from the American lectionary, so there are some discrepancies.
Meinrad Psalm Tone 8 (transposed) freely downloadable from: https://www.saintmeinrad.org/media/1486/modalpsalmtones-organ.pdf
using the first and last measure of the four-phrase version.
