The 1968 Italian documentary film "Sweden: Heaven and Hell" featured "Mah Na Mah Na" original title "Hooray For The Swedish Sauna" and the soundtrack by Piero Umiliani. Lead vocals were by Alessandro Alessandroni and Giulia de Mutiis. Alessandro also worked on soundtracks for Ennio Morricone. It's Alessandro Alessandroni's twang guitar on "The Good, The Bad And The Ugly" and his whistling on "A Fistful Of Dollars". The original "Mah Na Mah Na" was used often on The Benny Hill Show and The Red Skelton Show appearing later on Sesame Street. This version of "Mah Na Mah Na" peaked at number fifty-five on Billboard.

Frank Oz and Loretta Long introduced "Mah Na Mah Na" to an even wider audience. You're listening to the first incarnation of several Muppet versions. Wikipedia: "In 1969, the first season of Sesame Street featured a sketch featuring two Muppet girls voiced by Frank Oz and Loretta Long who are unsure of what to do, until they decide to sing a song, enter an unusual-looking short, shaggy-haired male Muppet character who begins singing "Mahna Mahna", prompting the girls to join him. None of the characters had names at the time, but the male Muppet who led the "Mahna Mahna" call-and-response was eventually given the name Bip Bippadotta, so as to distinguish him from the official Mahna Mahna character that would be developed later on. The Muppet character called Mahna Mahna was originally performed by Muppets creator Jim Henson, and is now performed by Muppeteer veteran Bill Barretta." The single was a top ten hit almost everywhere.
