There's another thread on Holy week polyphony, but here's one with a narrower focus. Having no sopranos so far express willingness to stay up Saturday night, I find myself making an ATB plan for this year's multilingual Vigil:

Jeffries: Praise the Lord, O my soul (B & bc)
Protege me, Dio mio (tone vi) (maybe chant-sur-le-livre)
Cantemus Domino ???
Te ensalzaré Señor (Californian tone)
Justitiae Domini ???
My beloved hath a vineyard (American Gradual)
Sicut cervus (maybe Pelham Humfrey's Like as the hart with 4-part full sections MTBr + bc; or maybe better Ockeghem for 2vv)

Dextera Domini (Feroci TTB)
