I basically took the 13 half hour episodes of the radio drama, cut off the intros and outros to each episode, killing the narration, and mixed together the episodes so they became 4 70 minute parts. I did it pretty seamlessly, I believe. The opening fanfare kicks off part one, and the closing credits ends part 4. Essentially, what you get is a more cinematic version of the Radio Drama, that I think flows a little easier and doesn't break up the mood into 22 minute chunks bookended by credits and narration.
I've done the same for Empire (10 episodes into 3 parts) and Jedi (6 episodes into 2 parts)
If you'd rather stick that on there, I'm pretty much officially volunteering it.
