Fortunately, Lucasfilm released a CD-ROM about 10 years ago helping to promote the Special Editions that had everything you wanted to know about the Original Trilogy Star Wars Universe (before it was commonly called the Original Trilogy) and then some, including an original and expanded black & white cut of the introduction of the cantina creatures (including a shot of Han Solo with a lovely lady lounging on his lap). It also featured three deleted scenes that originally introduced Luke Skywalker to the audience. In the end, deleting them from the final cut was a good idea, imo, but to leave them off the Extras DVD was just plain wrong. Take a look and see what you think.
LUKE'S ORIGINAL INTRODUCTION WITH THE LESS THAN RELIABLE TREADWELL
LUKE WITH HIS PALS IN ANCHORHEAD
This clip includes the 11th most underrated female character in the Star Wars movies: Camie (If you can't name the other 10 then you're not a True Star Wars Fan :p ). That look she gives Luke at the end of the clip... now if that wasn't sparks I don't know what is! :p
LUKE AND BIGGS TALK POLITICS
Man, I wish they were able to somehow keep this scene. It makes Luke's decision to join the Rebellion toward the end of the movie more of a clear decision he has been thinking of making for a longer period of time than deciding to join on because Fate (or a princess' pretty face) has pushed him in that direction.
EDIT: Because I only just discovered that Camie is spelled with one "m", not two.
