OK, folks, let's think logically about Ian's killer puzzle.
Scelsi - I can find the following titles in French (thanks to Wikipedia):
Chemin du coeur
L'amour et le crane
Il est grand temps
Meme si je voyais
Nuits
L'ame ailee
L'ame ouverte
Arc-en-ciel
Voyages
Et maintenant c'est a vous de jouer
...altho' he did say "reference in French" rather than "title"...
Lehar - Rose de Noel is, I see, an adaptation of pre-existing Lehar rather than echt-Lehar; none of the numbers seem to have a link with any of the Scelsi (apart from two, entitled Rendez-vous
d'amour and
Amour et giberne)
Hmmm, logic doesn't seem to be getting me very far...
I don't fancy wading through Bach and Mozart and I can't see any link with either Scelsi or Lehar with King Crimson!
Give us a clue! (please)
