Ever hear the Mah-Na Mah-Na Samba? The song was originally written by Piero Umiliani for an "art" film from the late 1960s called Sweden: Heaven & Hell and both variations appeared on the soundtrack.
AND the soundtrack album has been re-issued.

If it was a hit as wiki says, then I must have heard it, but I don't remember anything about it. Will have to check this one out.
