I guess there are no 'official' versions but there are demos of various numbers, most but not all of which were recorded several years ago. Many of the lyrics for these will have changed, particularly during the Broadway rehearsals.
Why don't you go? Why don't you leave Manderley? He doesn't need you... he's got his memories. He doesn't love you, he wants to be alone again with her. You've nothing to stay for. You've nothing to live for really, have you?
