il colosso (Brian version)

hi, i just want to understand, if soeone of you can help me, the truth abouth Il COLOSSO DEMO VERSION (or Brian vocal version); i've got no indication about the promo where it was relase (if there is a promo with it). I have some doubts about the authenticity because the tracks called so that i've eared are nothing than a edit version of the original track shifted (ptched) at -3 semitones (you can ear also the music and the voice of Sissel downtones); at least everyone can do this version.
can someone of you tell on what cd exist this demo (if exist).

thanks a lot

It's a fan made mix.
Not perfect, but does the job!

The promo releases with this track all feature the full-length album version if I am not mistaken. At least the withdrawn US shaped promo CD has the full version.

As pootle1 states, the 'demo' is not official. Just to show the Queen community that it's Brian who sings the lead for Pinocchio.

thanks for the clarification.
best regards
