This is the song that the Muppets made famous. But it was first heard in Svezia – inferno e paradiso, an Italian “documentary” about the Swedish sex scene in the swinging sixties. I put documentary in quotes, because the movie is even more staged than The Hills.
The “Mah Nà Mah Nà” song is used for a scene where a group of girls visit a sauna. It’s mildly unsafe for work, but not unsafe enough to be really interesting.
You know what’s awesome? In just one year, this song went from the soundtrack of what’s basically a softcore porn movie to Sesame Street.
