Both:

Sun goes down,
I'm just gettin' up,
I'm headed for the city of lights.

Radio blastin',
All the way to the club,
Gonna rock this town tonight.

Chipettes:

You're living in a man's world,
They tell us.

But we ain't gonna buy it.
The thing's they're tryin' to sell
Us, now.

Cause we're the girls of rock and roll
(Oooo!)
Yeah we're the girls of rock and roll.
Rock and roll.

Chipmunks:

Curtain's up,
And I'm ready to go,
My guitar is in my hand.

There's nothin' more that I'd rather do,
Than play in a rock and roll band.

What we have is what we will believe in,
Headin' for the top!
Don't you know?
We'll never stop believein'!

Cause we're the boys of rock and roll,
(You better believe it, yeah~)
Yeah, we're the boys of rock and roll.
Rock and roll.

Chipettes:
We are the girls,
We are the girls,
We are the girls of rock and roll.

Chipmunks:

We are the boys,
We are the boys,
We are the boys of rock and roll.

Cause we're the boys of rock and roll,
(Ohhh~)

Chipettes:

Yeah, we're the girls of rock and roll,
Better believe that we are...

Chipmunks:

Yeah, we're the boys of rock and roll
Rock and roll

Chipettes:

Yeah, we're the girls of rock and roll,
Rock and rock and roll

Chipmunks:

Yeah, we're the boys of rock and roll
Rooooock and roll

Chipettes:

Yeah, we're the girls of rock and roll,
Rock and rock and roll
