Sorry gang, a bit late to the party here. But, I also remember Anakin fighting Kenobi over a volcano, Anakin not knowing his wife was pregnant, Leia being a
princess because the Organas were Alderaanian royalty, etc.

And, I just came across this -

I think it's the original script for RotJ. Check scene 51. Ben's ghost is talking to Luke on Dagobah, and he gives Luke some extended dialogue about Anakin, their fight, the Organas, etc. Pretty cool and this is what I always thought as the back story for the OT. Surprised when Lucas changed it all for the crummy prequels :(
