High end audio test song (drumkit jam & bass)

[Joey45419]

Whats that song they always play to test high end audio? it's a jam with a drumkit playing a genesis/level 42 type beat and some guy doing wicked slaps and pulls on a bass. there's a keyboard but it's just there to back the two up. I remember, the song was on an old casette of mine called "drum demo tape for audio testing". My friend who borrowed the tape once said it was a sheffield labs recording. Anybody know? ::
