I genuinely hope that the ESB Tape still exists, such recordings are movie history!!!
Not from ‘Protocol Droid’, but there is a feature-length audio recording of the limited-edition screening from ESB that was taken during the 1st four weeks of the film’s release. The audio features alternate lines and sound-FX.
You can read the details, here.

You can download the individual audio files of that screening from the uploader’s blog:
