Well going by the evolution maybe John Williams is the complainer. (kiddin' of course but...) In the first version he's given a scrolling credit with the London Symphony right up close. The "second" version has Williams with some breathing space between him and the symphony, then going to ESB he gets his own stationary credit, then a few seconds later the symphony shows up. The record was a huge seller why not reward that in the credits revisions.
