Leather & Lace (Jason Nevins Mash) being illegally sold; is the vocal from a reel?

[GoldDustOrphan]

This is only a clip, but it's a high quality clip. I can't figure out what vocal he used for this. I don't think it's the album version, but an acapella from one of the reels.

Oh, and the person (DJ Michelangelo) who did created this mash (Stevie's vocal against a familiar remix track by Jason Nevin) is selling the track on a website called dramamix.com. He's already infringing on the copyrights of two people (Stevie's and Jason Nevins'), but selling it is gross.
