whats the lyric to that Muppets song you know Renault, renault, da da, dah da dah

Mahna Mahna originally titled ''Mah-Na Mah-Na,'' was written by Italian composer Piero Umiliani for a Swedish documentary called Svezia, Inferno e Paradiso (Sweden, Heaven & Hell). It is a nonsense song that achieved widespread fame when the Muppets performed it.
The Muppets' rendition of ''Mahna Mahna'' debuted on The Ed Sullivan Show in 1969, performed by Mahna Mahna & his back-up singers, the Snowths. This version of the skit was restaged for episode 101 of The Muppet Show.

A slightly different version of the skit was first performed on episode 0014 of Sesame Street by Bip Bippadotta, backed up by two Anything Muppet girls. Whereas the Snowths sing ''doo doo doo doo doo'' on The Ed Sullivan Show & The Muppet Show, the back-up singers on the Sesame Street version sing ''ba tee pa tee pee''. This version was also used during the closing credits of an episode of Play With Me Sesame, with the cast singing & dancing along as this clip played. It was also included in the broadcast version of The Street We Live On.

Although it is currently unclear which of the aforementioned clips aired first, as air dates for episode 0014 of Sesame Street r unavailable, it is very likely that the clips aired within days of each other. Because the Ed Sullivan Show appearance was on live television, however, the evidence suggests that the Sesame Street version was filmed first.

You pain in the ass, you've got me humming that tune now! :)

Occasionally l would go into the office humming manamana. The others could not help themselves and l had the satisfaction of hearing them humming/singing it to themselves all day. Another one was the duelling banjos.
