"An Italian Film soundtrack composer, a Swedish porn film, and the Muppets. What's the connection? The answer is four words ? Mah na mah na. Okay, they?re not even proper words, but bear with me.

In 1977, those loveable family favorites the Muppets had a world wide hit with the song Mah na mah na. Where did this song come from? (...) Piero Umiliani wrote this tune in 1968,as part of the soundtrack for a Swedish porn film called Sweden; Heaven or Hell."

But there were other versions before that: "One came out back in 1971 behind the (then) Iron Curtain in what was then Czechoslovakia. Singer is Pavel Vitoch, acc.by the Dance Orchestra of Czechoslovak Radio, cond.by Josef Vobruba. Czech title is 'Mana, mana', and the single is on SUPRAPHON records' label #043 1195."
