Barge Fight
About this scene:
On board Jabba the Hutt's barge, Threepio has found himself an unwilling translator/mediator between a drunken Ree-Yees and Saelt Marae (aka Yak-Face). Salacious Crumb joins in the fun as well. The altercation ends in fisticuffs, just before Threepio bumps into Artoo serving drinks.
This was just a little extra action taking place aboard Jabba's barge, but it was cut from the film as it was non-essential to the storyline.
Pictures from this scene show up all over in various places, including in the photo insert from the novel. Also, the scene is described in the novel, but it is Ephant Mon rather than Saelt Marae who gets in the fight there.
