Louie Louie
"Louie Louie" is an American rock 'n' roll song written by Richard Berry in 1955 and best known for the 1963 hit version by The Kingsmen. It has become a standard in pop and rock, with hundreds of versions recorded by different artists. The song was originally written and performed in the style of a Jamaican ballad. It tells, in simple verse–chorus form, the first-person story of a Jamaican sailor returning to the island to see his lady love.
