I have never watched the 2004 DVD of the OT nor do I intend to but I am curious about the audio commentary tracks. For those who have listened to them, does GL go into any details about WHY he added certain scenes or does he just focis on the technical details of the new or re-done scenes? I would be very curious to hear if there's ever been any logical explanations to why certain inserts or re-dos exist other than 'because my vision changed' or 'becasue I wanted to- nanny-nanny-boo-boo'.
