>Yes, but these are not cassettes of Books on Tape but recordings of the Hitchhiker's original radio show (in Britain).

I actually used to have the original BBC (I think) radio broadcast of HHGTG on mp3 while I was in college, but that CD must have been misplaced when I moved here. The mp3 files had more than just a guy reading a book, there were sound effects and multiple voice actors. I think you can buy the radio broadcast on amazon, and if you can't find it there I am sure it can be found on ebay
