Hey A-RoN,
As the vocalist in this remix, I can safely say that no vocoders were used. What you're hearing is vocal harmonies, even then, there's only pitch correction on the higher vocals (and the high pass effect sections.. for effect, and not for smoke and lights) as I was having to sing in falsetto (due to having a naturally deep voice).
I hope this clears some things up.
Also, thank you very much everyone for your comments, I really appreciate everything you've said and are saying about this remix. They certainly bring a smile to my face, especially that surprise comment from Lee Brotherton himself. Thanks Lee!
