From a web page I googled:
Just what was Jack Ely saying when he sang Louie, Louie? Well, as originally written by Richard Berry, here it is:
Fine little girl she waits for me
Me catch the ship for cross the sea
Me sail the ship all alone
Me never think me make it home
Louie, Louie, me gotta go
Louie, Louie, me gotta go
Three nights and days me sail the sea
Me think of girl constantly
On the ship I dream she there
I smell the rose in her hair
Louie, Louie, me gotta go
Louie, Louie, me gotta go
Me see Jamaica moon above
It won't be long, me see my love,
I take her in my arms and then
Me tell her I never leave again
Louie, Louie, me gotta go
Louie, Louie, me gotta go
Seems innocent enough to me. If somebody else added a few dirty lyrics later, I don't see why that should put the song out of bounds.
Man, those were the days...LSD trips galore!!...sarcasm... ;o]
My fragmented recollection of the famous Kingsmen version bears no resemblance to those lyrics beyond the words "Louie, Louie". The famous version contained a refrain "Louie, Louie, Lou-EYE" followed by a line that rhymed with EYE (maybe a different line each time), and also contained something like "makes no difference if it's black or white".
