"I really don't think Sondheim would have done a very good job with it, and I think it really needed the big orchestrations that Lloyd Webber for the most part delivered upon."
Well if you're incinuating that Sondheim can't do big orchestrations, you're very wrong. And that's really a collaboration between the orchestrator and the composer. Listen to Follies and then tell me he can't write grand compositions.
I still think Sunset Boulevard written by Jerry Herman would have been sensational.
