Need help...Stevie Wonder song? (hey, not a war thread!)

Anyone here a Stevie Wonder fan? I'm trying to track down this song (have been for while now).
I'm about 90% sure it's Stevie Wonder because a) I thought I heard someone actually say it one time and b) it sounds like something from that whole "Superstition" era. It's VERY funky.
It's an instrumental (at least all that heard of it), so with no lyrics to quote, this might get tough. But some of you into music and instruments might be able to nail it down.
It's mid-tempo, real heavy on the 1 beat. There's a real prominent clavinet (is that what that instrument is called? It's a real cool "honky/quacky" sounding keyboard thing...it's the instrument that plays that main lick/hook in "Superstition"...you know if it if you hear it).
This song just seems to repeat a simple progression over and over again. I don't know the chord symbol number thing, but if the song was in, say, E it would go from E to D to A (kind of a descending/reverse I-IV-V progression).

I'm f***ed, ain't I?
Sadly, I have nothing else but that to go on.
I asked a question like this a year or so ago (a Smiths song) and many of you nailed it right away.
Any help is appreciated.

No luck.
I mean, there's a TINY chance it's not even him, but I'd put money on it. I heard it back last summer as bumper music on Rush or somebody and I think he even said "...Mr. Stevie Wonder playing us back in..." or something. Then I heard it on a movie. Not "Dazed and Confused", but something like that (set back in the 70's).
Then, just yesterday out of the blue, I was listening to some syndicated sportstalk radio show late at night and they had it playing and it all came back to me and I remembered how cool it was.
So, I THINK it's Wonder, but sadly all the songs on his albums at amazon/cdnow aren't available for listening samples. Just the first five or so.
This would SO much easier if it had lyrics, I know. I mean, it doesn't help anyone for me just to go "beyowng...chick-a-bow-dow...beyown-chank-a-a..."

True 'dat
Anyone?
... suddenly these jump to mind as candidates for radio airplay
higher ground (red hot chili peppers version not as good as Basso Mix)
i wish (also subject to almost as many cover versions as superstition)
living for the city (extended version over 7 minutes... lots of instrumental bars)
www.allmusic.com might help prompt names and album reviews, but almost no audio samples
you might have to search the soundtrack listings of all last years retro movies for prompting

actually that description (which i didn't see the first time i scrolled through) sounds life
rufus - tell me something good
which has lyrics but large instrumental portions as well

I'll go check...
Superkaratemonkeydeathcar, YOU, my man, are the head m.f. of ALL the m.f.s
Thank you, thank you, thank you!!!
I just assumed it was Stevie Wonder. I even know Billy Preston (not personally, but am pretty aware of him) and it never occurred to me that it might be him.
In any case, you're the man. My eternal props!
I also recommend u the Ray Baretto coverversion of the song "pasttime paradise".
