what song is playing?!?!?!?

its when beatrix first gets up the stairs to pai mei.. and they start fighting " tiger crane eagle claw" and its this tight 70's funk ninja music.
WHAT IS THIS SONG? iv been looking for so long its not on the soundtrack please someone tell me if you know it.

Isaac Hayes - Three tough guys

If im not in error

Its the instrumental version thats used in the movie

i think three tough guys is the album name, i cant find any songs called three tough guys but thanks alot.... anyone else out there have any suggestions??

I found a version of the song on the Super Bad Super Black: Can Y'All Dig That? album, but it didnt sound like the version I downloaded.
And its called 3 Tough Guys to be exact. The original version has got vocals on.

Cool. Question answered, closing.
