This is a setting of the wonderful spiritual simply played on the Caen.
Registration:
Recit: Viole de Gambe, Voix Celeste
Positif: Cor de Nuit, Salicional, Unda Maris coupled to Recit
Grande Orgue: Flute Harmonique & Bourdon 8
Pedal: Soubasse coupled to Recit
At the end I couldn't resist adding the 32 Bourdon - a bit too much probably.
