First off, to the best of my knowledge, nothing was sold at the Wednesday event. It is not immediately clear why. I know no reason why there was no activity before the service; after the service, there followed almost immediately a harpsichord recital, so at a guess that was why there was no relaxed milling about the sales table between the musical events.
So all the Henningmusick merch which moved, moved on Thursday. There were sold:
1 copy each of the SSA & SATB versions of the Alleluia in D
all 20 copies of Love is the Spirit
two copies of the Three Short Pieces
one copy of the Organ Sonata
So, a little better than half of what was on offer. Satisfactory.
