I heard this song on the radio a number of times, probably around 1982 - 1986. It's a french song, I believe, and the male singer had a rather deep voice. The song is fast and interpreted in a funny, almost comedian way.
The title could be something like "Le Zett" (the french letter Z). The verse is something like:
(ta ta) le zett (ta ta ta ta ta taa) le zett (ta ta ta ta ta taa) le zett (ta ta ta ta ta) le zett
And I remember that in the bridge a race-car appeared.
I have been looking for this song ever since the internet age with no luck. It can't be so uncommon though, since it was played multiple times in a mainstream radio station.
My only other option is to upload me singing the "le zett" but that would probably make it even less recognizable than the "ta tas".
In my memory it was a very catchy song, but I was 13 or so back then so it might as well be total crap.
Edit: I tried to recreate the melody (the beat bits at the end do not sound like the original song at all, but the melody does - I think). Soundcloud:
