CWB II has some traditional hymnody for these occasions. I note they always use tunes that fit well enough but are not the most commonly used settings.
420 Let All on Earth Their Voices Raise
CWB II says this is based on Exultet caelum laudibus but does not mention the author/translator. Other sources say it was written by Richard Mant and the text with minor variations is at Hymnary. Here it is set to OLD 100th but TALLIS CANON is the more common setting.
421 Th’eternal Gifts of Christ the King
C4th Latin text by St Ambrose: Aeterna Christi munera, translated by John Mason Neale and here set to DEO GRACIAS. The text is at Hymnary.
422 Sing We Now the Glorious Martyrs
This text is by Genevieve Glen OSB and is in the preview at OCP. There it is set to IN BABILONE but in CWB II they use STUTTGART.
423 By All Your Saints Still Striving
This is by Horatio Nelson and is set to AURELIA in CWB II. They give a whole page of specific texts for saint’s days that replace the second stanza. The text is here.
424 This is the Feast Day of the Lord’s True Witness.
This is a translation of a C8 Latin text Iste confessor and set to ISTE CONFESSOR (OK, I suspect that is its usual setting this time.) I can’t find the specific translation used here online.
