Just found this while searching for sounds for my own edit.

"In The Sounds of Star Wars, an aurally astonishing and visually engaging book, New York Times best-selling author J. W. Rinzler reveals the illuminating history behind the sounds of the Star Wars universe. With behind-the-scene stories, photographs and sound clips, fans will discover the origins of sounds from their favorite scenes. An attached sound module with an exterior speaker and headphone jack lets readers listen to more than 250 unique sound effects. More than 300 photographs illustrate the Saga's many memorable scenes."

It would be a lot more straightforward (and less kiddy) if they'd included all the sounds on a CD, however I'm sure there's some technically minded folk out there who could jerry-rig a means to extract the sounds from the module (or just use the headphone jack to record directly). I'm assuming the sounds are of a decent enough quality if they've thought to incorporate a headphone jack.

This'd truly be my (and any fan editor's) dream come true, and would come in handy for any of Ady's future edits.
