These may be available on the DVD, but here is a site with a large number of deleted and production Star Wars scenes. Episode 4 for you super nerds. If it is real the biggest bit for fans is the scene where Luke scurries to Biggs' place and meets his posse. Biggs plays the wise old man to Luke's callow youth. Much of the rest are slight variations of things you have already seen. It's a cliche, but these movies have really lost something since the travesty of the prequels.
