You wanna know
Who's gonna go
Who's gonna show
You wanna say
Maybe next time

You say you might
Stay in tonight
But I will say
you're out of your mind

If you won't come to the party
On grounds of nothing to wear
All the beautiful people
And I will be there

You wanna find
Some private time
You underline
The week has been
Grinding you down

But if you go
I'm gonna show
Just how I feel
I'm head over heels

If you won't come to the party
On grounds of nothing to wear
All the beautiful people
And I will be there

And when I arrive
I look for your eyes
I'm hoping to see
You looking for me
