Olivia, Toni Tennille, Tina Turner:
Somebody's gonna hurt someone
Before the night is through
Somebody's gonna come undone
There's nothing you can do

Toni: Everybody wants to touch somebody
Tina: If it takes all night
Peaches: Everybody wants to take a little chance and make it come out
right

All:
There's gonna be a heartache tonight, a heartache tonight, I know
There's gonna be a heartache tonight, a heartache tonight, I know, I know

Toni: There's gonna be a heartache tonight
Tina: And the moon is shining bright
Karen Carpenter: Turn out the light, we'll get it right
All: Heartache tonight, Heartache tonight, I know

Olivia and Karen:
Some people like to stay out late
But some folks can't hold out that long

Peaches:
But nobody wants to go home now
There's just too much going on

Toni: This night is gonna last forever
Tina: It's gonna last all summer long

Olivia:
Some time before the sun comes up
The radio is gonna play that song

All:
There's gonna be a heartache tonight, a heartache tonight, I know
There's gonna be a heartache tonight, a heartache tonight, I know, I know

Karen:
We can beat around the bush
We can get down to the bone
We can leave it in the parking lot

Olivia: Either way, there's gonna be

All:
A heartache tonight, a heartache tonight, I know
There's gonna be Heartache tonight, heartache tonight, I know
There's gonna be Heartache tonight, heartache tonight, I know
