This setting of Psalm 62 was written by Francis Patrick O’Brien, a priest with a suitably Irish sounding name from Boston, and a song that turned up at Ryan’s parish recently.

I have a copy in Ritual Song 643 and the sheet music can be purchased at GIA in an inexpensive collection. GIA also have a snippet to listen to.
