It was on a compilation album I had (essential hardcore or heavenly hardcore or suchlike). Goes like this:
E (pronounced eh) Ecstacy
sky's the limit and you know that you can have what you want
E - ecstacy
skys the limit and you know it
The girl starts singing - woh-oh-oh-oh (in the way they did then)
I know its a long shot, but someone once named me a song on here from one line so Im keeping my fingers crossed
