Ievan polkka

"Ievan polkka" (Savo Finnish for "Ieva's Polka") is a popular Finnish song with lyrics printed in 1928 and written by Eino Kettunen to a traditional Finnish polka tune.

Very popular after World War II, the song was almost forgotten during the late 1970s and 1980s.

The a cappella version of the song acquired greater international popularity as part of an Internet phenomenon in the spring of 2006 when the Loituma Girl (also known as Leekspin), a looped Flash animation of anime character Orihime Inoue from the "Bleach" series twirling a leek, set to a scat singing section of Ievan Polkka sung by Loituma was posted in Russian LiveJournal. For the animation, only the second half of the fifth stanza (four lines) and the complete sixth stanza (eight lines) are used. It quickly became a global hit and the song soon enjoyed overwhelming popularity as a ringtone. Since then the song has been circulating and known under several misspelled variations of its original name or references to the animation, including "Ievas Polkka", "Levan Polkka" and "Leekspin Song" (the second of which being the result of similarity between the sans-serif lowercase L and uppercase i).
