The original is 'The Source feat Candi Staton' http://www.discogs.com/release/66632, it's a mix of 'Your love' by Frankie Knuckles with a Candi Staton acappella over the top and they fit together like carrots and snowmen. Absolutely wicked record.

No idea on the mix you're on about though I'm afraid. Get the original it's wicked. 10p at a car boot near you if ya lucky.
