What about "Droid World" or "Planet of the Hoojibs?" Anyone have these two either? These were book & cassette sets from the early 80's. They were both based on stories from the Marvel Comics SW series.
"We Don't Do Weddings..." and "Nightlily..." were cassettes (at least Nightlily may have been available as a CD, but I don't know about the first one) from the late 90's based on short stories in "Tales From the Mos Eisley Cantina" book.
As far as "The Mixed-Up Droid" goes, I don't know much about it except that it is a childrens' story. It was released in the 90's but I think that was a reissue and it was really originally from the 80's.
Also, a question about the "Rebel Mission to Ord Mantell" audio drama described here: http://starwars.wikia.com/wiki/Rebel_Mission_to_Ord_Mantell
The above link shows a scan of what appears to be the tray inlay from a CD jewel case as the "back cover." But as it was published by Buena Vista Records in 1983 I highly doubt that it was ever released on CD and that therefore that inlay scan must be a fan-made item made using the back of the record packaging which may have been a book, but I don't know for sure because there are no scans of book pages here: http://www.theforce.net/timetales/misc/arcana/arcana-1983.asp
In fact, for the back image theforce.net has the same apparently fan-made CD case inlay that the wookieepedia article has. I suspect it is a book and record or cassette set like "Droid World" and "Planet of the Hoojibs." But info on this item is scant online, any help would be appreciated.
