(words & music by Johnson - Penniman - Blackwell)

Gonna tell Aunt Mary 'bout Uncle John
He says he has the blues but
He has a lotta fun
Oh baby, yes baby, whoo-oo-oo-oo baby
Havin' some fun tonight yeah well!

Long tall Sally has a lot on the ball
And nobody cares if she's long and tall
Oh baby, yes baby, whoo-oo-oo-oo baby,
I'm having me some fun tonight

Well, I saw uncle John
With long tall Sally
He saw Aunt [bad word] 
And he ducked back in the alley
Oh baby, yes baby, whoo-oo-oo-oo baby
I'm havin' some fun tonight

We've gonna have some fun tonight
Gonna have some fun tonight
We're gonna have some fun tonight
Everything will be all right
We're gonna have some fun
Gonna have some fun tonight
