Well TServo's post was pretty much spot on, and would answer any questions that followers of this project may have about the mono mix.
However the three or four posts earlier on this page that give inaccurate information from unreliable sources are only going to perpetuate confusion. I was therefore linked to a thread where this has already been discussed and debunked.
Answers to questions about the other sound mixes on Harmy's release may be found here.
