Some composer did
provide additional score, including John Williams
orchestrator, Conrad Pope
(I think I read like 20 minutes).
Right at the time when Haslinger's score was rejected, Elfman had already recorded Alice, so that's sort of an industry excuse. I think the real reason is Elfman had "better" things to do and didn't want to come back to the film.
As I write this, there may be little pieces of Haslinger's score left in the film when it is shown.
VareseSarabande.com is releasing Elfman's score, and there are samples.
