I've found a quality trance tune but can't work out what it is, as it is in the middle of a mix. I think the mix is called Cancun Spring Break 2000. The lyrics are:

"At midnight under the full moon, they danced naked, worshipped the devil, and drank blood, we call them witches, we can't see them, but we can hear them, shhh, can you hear them?"

I would be grateful if someone could help me on this one.
