Hey Pupster, the old article linked from Queenonline (
web.archive.org cache) stated that the initial disc was produced only for promotional DTS press kits at CES Las Vegas in 2002, and that by the time it took place, May had already undertaken the changes which resulted in the eventual retail release. The article is not complimentary of the original disc's mix, nor of its authoring.
If you need to confirm your own copy,
the Discogs page for this release has all the information you'll need. Mastering code IFPI LL07 is unique to these discs, I understand.
FWIW, I also struggle to enjoy Bohemian Rhapsody ... not sure whether I should blame my peers for always playing it at houseparties in our youth, or Mike Myers.
