Here's another Iko Iko version performed by Aaron Carter. This version is similar to The Dixie Cups.

My grandma and your grandma
Were sittin' by the fire.
My grandma told your grandma
"I'm gonna set your flag on fire"

Chorus:
Hey now! Hey now!
Iko, Iko, unday
Jockamo feeno ai nan?
Jockamo fee nan?

Look at my king all dressed in red Iko, Iko, unday.
I betcha five dollars he'll kill you dead
Jockamo fee nan?
Chours

My flag boy and your flag boy
Were sittin' by the fire.
My flag boy told your flag boy
"I'm gonna set your flag on fire"

Chorus

See that guy all dressed in green ?
Iko Iko unday
He's not a man He's a lovin' machine.
Jockamo fee nan?
Chorus x 2
Fade to end

You can tell that the verse that mentions "king" isn't authentic to the Mardi Gras Indians, since those groups called their leader
"Big Chief" and not "king".

And it occurs to me that the "see that king dressed in red" and
"see that guy dressed in green" reminds me of the dressed in color verses in the spiritual "Wade In The Water"...
