Chorus
Hey now (hey now)
Hey now (hey now)
Iko iko un day
Jockomo feeno ah na nay
Jockomo feena nay
[repeated twice]

My spy dog see your spy dog
Sitting by the Bayou
My spy dog see your spy dog
Gonna set your tail on fire

[chorus]

Indian boy going down town
Iko iko un day
You don't like what the big chief said
Said Jockamo feena nay

[chorus]

My grandma see your grandpa
Sitting by the Bayou
My grandma see your grandpa
Gonna set your flag on fire

[chorus]

My spy boy see your spy boy
Sitting by the Bayou
My spy boy see your spy boy
Gonna fix your chicken wire

[chorus]
