I have done a lot of the Lent songs in CWB II already:
288 Forty Days and Forty Nights
289 From Ashes to the Living Font
290 God of Mercy and Compassion
293 A Trusting Psalm
This is another fine text by Ralph Wright OSB, who seems to be a favourite of CWB II editors.
You can find the lyrics in the free download St Michael Hymnal (no 620).
Here it is set to ST BERNARD.
I had to get the chords from Together in Song, which reminds me that its melody line edition has many advantages over the accompaniment edition of CWB II – size, price, chords, etc. I got the bass notes from CWB II to make the backing better, but I could have got them from Hymnary as well.
