Experiments with adding a verse to the Quoniam did not get very far. I have now finished recording this and mixed the tracks. Listening to this led me to swap some lines between the lower voices (tenors/basses) and upper voices (sopranos/altos) in the fugal section of the first half of the verse. This reverses a decision I originally made to give the voices a different role in the first half of the verse to the second (mainly to add variety) but the effect of moving between upper and lower voices is now improved and there is a better balance to the first half of each verse. The Quoniam track is all mixed.
