The interesting thing though is how superbly acted Alec Guinness is, in the scene in ANH when he talks about Lukes father and Darth Vader. In that the response, makes it seem that Kenobi was considering his words carefully and there was a lot more to the story. If you know what I mean?
@Tyrphanax
Are there any sources for the OT EU prior to the Prequels, I've heard that Lucas contradicts a lot of the previous work, but unfortunately I've never seen/read the ideas that pre-dated the Prequels.
