I hesitated to answer this for fear of confusing an already confused situation. However, setting aside the contradictory statements in various LP and CD sleeve/booklet notes, the situation is not so complex:

1, 2, 3, and 5 were sung by the baritone Harry Plunket Greene (so says the score), hence the low key would be the original and the low keys of the following chorales are convincing in their voice ranges

4 was sung by the soprano Agnes Nicholls (so says the score) and the high voice version of the chorale is convincing in its voice range

No copy that I have seen of no. 6 names a singer. I have stated in my article the reasons for which I believe the high voice version is the original. One point among many, the organ writing in the low version of the chorale goes off the bottom of a normal pedal board.

These notes on the score are the only evidence we have that at least the first five were sung in Stanford's time at all. So far as I know, nobody has actually traced a performance of any of them by Greene, Nicholls or anyone else until fairly modern times.

Going by this, I presume that a performance that comes as close as possible to Stanford's intentions would:

- use adult solo singers for the songs (baritone in 1-3 & 5, soprano in 4 & 6)
- sing the chorales in the same key as the preceding songs

Put that way, it doesn't seem so very complicated or so very difficult to organize, though if Mr. Woland intends to perform it that way later this year he may be the first to do so.

I thank Mr. Woland for his elevating me to the dizzy heights of a doctorate, but I fear that a Bachelor's Degree with Honours (from Edinburgh University) is the height of my academic achievement.
