I addressed what I felt I should address. Personally I don't find this score any closer to Orff than I find E.T. to Prokofiev or a lot of his stuff to Stravinsky, Shostakovich or Mahler, so I didn't think the point merited any more special attention, and I agree about the space wizards.
I disagree strongly about the Lucas point. It doesn't matter that he is the culprit behind 'Howard the Duck' or 'Slipstream' etc. He is the experienced director and producer of his film and if Williams thought he was crap he simply would not work for him. I don't see Williams as an inexperienced petulant youngster that will - as you put it - "stand up to him"... There is a difference between being a 'Yes-Man' and 'Standing-Up' to directors. In this case, those two know each other very well and I am sure they discussed everything very professionally and cordially and even if we don't know whose idea the choirs were, it was Williams' duty to deliver what the director wanted, unless it really went against his grain, it obvioulsy didn't. And of course he takes full responsibility. Plus, like I said, in my opinion the other 100 minutes or whatever of the soundtrack are just beyond professional and the call of duty.
'Schindler's List' left me rather cold in all respects; I don't think Spielberg is the director for that kind of thing, and Williams, again the consummate professional, turned in the best he could in an area that really isn't his strength at all (lyrical heartfelt melodies). If he didn't walk away from that (let alone getting an Oscar for it, but we know how those work), I don't see how he would have a problem with the 'Duel of Fates'.
