In GIA Unbound this is a very new version of an very old text to a very old tune. Alan J. Hommerding has created his take on the “The Prayer of St Francis” for the eight hundredth jubilee of the saint. He set it to TALLIS’ CANON.
As always, the sheet music can be purchased at GIA, where the text is in their preview.
GIA Unbound does have a YouTube page but none of the ones I chose are there.
