I found my old audiocassettes of the original broadcasts and found to my surprise that there was an additional scene in the first episode between Luke and Camie that I vaguely remembered but isn't in the Highbridge version.
Are there any resources outlining the differences between the broadcast and Highbridge versions?
They also edited Ken Hiller's intro “Star Wars. An adaptation for radio in thirteen parts, based on characters and situations created by George Lucas. Episode____” to just “Star Wars. Episode____.” The original introduction was more theatrical.
