Domine Deus Agnus Dei and a closure

I have settled on a shorter introductory section to open the piece so it now has this structure so, instead of a simple A-B-Ch, A-B-Ch structure (Ch being the chorus) it is A-Ch, A-B-Ch, A-B-Ch. I finished writing this and recorded an mixed this – in the end (for the time being at any rate) omitting the separate sung bass line in the verses as this (together with the melody doubled by sopranos and tenors) overwhelmed the main tune carried by the altos.

I printed all four pieces and put these through my friend’s letter box together with a birthday card and all with four hours left on deadline day. This gives me some sort of closure on this piece which, I think, I needed.
