Ievan Polkka

Background
Ievan Polkka (Eva's Polka) is a song written in the 1930's, set to a traditional Finnish melody. After falling from popularity it was revived by Finnish band Loituma in the 1990's, and in 2007 a cover by Otomania was released, voiced by Hatsune Miku and accompanied by a video illustrated by Tamago.

At the time there was a popular internet meme called Leekspin, which was based on an animation of Orihime Inoue from the Japanese manga Bleach twirling a negi to an infinite loop of the 5th stanza of "Ievan Polkka". Riding on the popularity of the meme, Hatsune Miku's cover of "Ievan Polkka" became her first popular work. Since then the song has been covered countless more times by other Vocaloids; numerous versions exist, including solos, duets and even a quartet mimicking the original.

The accompanying video to Miku's cover of "Ievan Polkka" features Hachune Miku (はちゅねミク), a blank-eyed doll-like chibi version of Miku. In the video, she waves a negi (also called a Welsh onion or spring onion) in time to the music, establishing the negi as Miku's signature item. Many Vocaloid fans mistake the negi for a leek; however, although a negi does resemble a leek, they are two entirely different vegetables.

The song is featured on the albums Hatsune Miku 1st Song Album, VOCALOID2 MAXI Single Vol. 1 ～みっくみくCDにしてやんよ～, 初耳, and 初音ミク-Project DIVA-F Complete Collection.

Triva

 * Miku's Ievan Polkka video outshone Inoue's original Leekspin animation, and as a result, when viewers spotted the Leekspin reference in Phineas and Ferb, they credited the reference to Miku and not Orihime.
