"Mah Na`; Mah Na`;" is a well-known pop music song, written by Piero Umiliani. It was a hit in many countries in 1968–1969. In the U.S. It peaked at #55 in the Billboard Hot 100 singles chart and #44 on the Cash Box magazine chart in October 1969. The song's lyrics contain no actual words, only nonsense words resembling scat singing. The original version interpolates melodies from "Swedish Rhapsody" ("Midsommarvaka" ("Midsummer Vigil")) by Hugo Alfvn, "Santa Lucia", "Boogie Woogie Bugle Boy", the jazz standard "Lullaby of Birdland", and others.In 1976, the first episode of The Muppet Show to be recorded (featuring Juliet Prowse), used "Mahna Mahna" as the first sketch. It was performed by the Muppets "Mahna Mahna and the Snowths". As a result, the original Piero Umiliani recording finally became a hit in the UK, where the Muppet Show soundtrack album featuring the Muppets' version went to number one.
