The Prelude has been written 1931 in the Thomaskirche at Leipzig as a hommage to JSB. It was already recorded for CB in 2012 by Agnus Dei:

I don't intend to compete with Dave's rendition. Interestingly, our experiments with the solo registrations independently came to nearly the same result... (I was not aware of Dave's recording before):
Basson-Hautbois 8 + Diapason 8, accompagnied by Cor de nuit 8 + Salicional 8
