Ryan’s parish used this Christopher Walker tune recently. It is a setting of Psalm 33 and the refrain is singable. The verses, however, will need a practiced cantor because the tune goes in weird and wonderful places.
The sheet music is available at OCP where the text is in their preview. You might want to listen to the song sample there to get an idea of what is going on as a glance at the sheet music may be somewhat daunting.
I hope my backing gets it right.
