I have no idea, they had some rather strange tweaks in their material. The previous song we did from Queen was Another One Bites The Dust and I'm pretty sure on that they sped up the recorder after they recorded it, to bring it half a step higher and give it a higher, tighter feel.

Those harmonies kept us from releasing this for literally years, before we got some help in decoding how they actually go. They're way more complex than it sounds, really weird melodies in the backing vox.
