I have been asked to put together the music for Compline/Night Prayer on Holy Thursday. According to Christian Prayer (my full Latin post-VII Breviary is packed away somewhere), the model is Sunday after evening prayer II. This will be a hybrid in terms of language, e.g., antiphon, responsory, canticle probably in Latin, text of Psalm 91 in English. Here are my questions: where do I find the responsory, "For our sake Christ" and which setting of Te lucis should be used? For Te lucis, I have settings for the evening of a solemnity (I'm guessing the vigil), for Sunday, for feasts, for memorials, for weekdays, and for Lent. Sigh.

All assistance is gratefully received.
