Its a track from the Pump Up The Volume, History of House Music documentary that was on Channel four that you can watch at this link: http://stage6.divx.com/user/pepitop...part-one-of-two

The song in question starts at about 23:00 when they introduce Ron Hardy and the Music Box.

There is talking over it and they didn't put up a title heading at the bottom to tell you what the song was, but its pretty hard to miss.

Any help would be appreciated, thanks.
