(Can anyone name the manufacturer of the organ?)
Here are the names of the organ stops, seen just before Howie brings the dead hare to Lord Summerisle and Miss Rose in the middle version but not the director’s cut or the short version. (screencap)
sub bass (16 ft)
salicional (8 ft) - "These names, of which Salicional is by far the most common, derive from the Latin salix, meaning willow"!!! (Encyclopedia of Organ Stops)
flute d'amour (4 ft)
lieblich gedact (4 ft)
voix celeste (8 ft)
and one more I can't read (probably a 16 ft pipe).
