Louie Louie was written by Richard Berry, who was also with the Robins/Coasters. He narrated “Riot in Cell Block No. 9” IIRC.
The lyrics in the Berry version are Caribbean patois but entirely understandable.

If you know the words Berry wrote you can hear most of them in the Kingsmen’s version.
The RICHARD Berry song was inspired by an earlier CHUCK Berry song, Havana Moon. Whether Havana Moon was an old sailor song I don’t know.
