Psalm 102: a paraphrase

I'm very fond of this tune. This is a good example of fine a capella singing of a Psalm paraphrase. Singing the Psalms is a skill which catholic Christians have lost, and I would like to see recovered. (Technically, of course, this is not Psalm singing: it's a paraphrase. By psalm singing, I mean the word-by-word singing or chanting of the straight text of the Psalm. This is to Psalm 102 what Luther's Mighty Fortress is to Psalm 46).
