If anything, James now sounds better. If you know the history of his having a few YEARS of recovery to his throat after food poisoning, it is understandable that he had some bad nights but now he is doing even the old material as well if not better. Just saw the show in SF and he pulled off all the material perfectly including hitting the high notes dating back to some of the Images and Words material.
Also, I agree with the other comments that Kevin Moore should perform with them for the anniversary DVD. Even Sherinian, who was FIRED, and Domenici who left over creative differences worked with them again. It's not like Kevin is abandoning his direction to sit in on one or two tunes.
