yes , It is strange for me as well as I was listening to The Empire Strikes Back Radio Drama on Friday ! I like it a lot though John Lithgow as Yoda is strange and takes some getting used to, also strange is that a very young David Allen Grier voices Boba Fett .It is shorter than the original radio drama but Mark Hamill , Billy Dee Williams and Anthony Daniels reprise their roles . The Jedi drama is ok but only Anthony Daniels is in it , it makes a lot of references to Shadows Of The Empire which I thought was cool .I also have the book of the Script which was published by Del Rey for The Empire Strikes Back in 1995 , it is illustrated throughout with Johnston and McQuarrie storyboards and some of the dialogue is different to the commercially released tapes and cd’s . There was an article I read on the differences somewhere , wish I could find it …would love to see it if anyone has it .
