[Verse 1: Luke]
It's been a really, really messed up week
Seven days of torture, seven days of bitter
And my girlfriend went and cheated on me
She's a California dime, but it's time for me to quit her

[Pre-Chorus: Calum, Luke]
La, la, la, whatever
La, la, la, it doesn't matter
Oh, well
"What are you guys doing?"
"We haven't even started the chorus yet"

[Chorus: Luke, Luke & Calum]
We're going at it tonight, tonight
There's a party on the rooftop top of the world
Tonight, tonight, and we're dancing on the edge of the Hollywood sign
I don't know if I'll make it, but watch how good I'll fake it
It's alright, alright, tonight, tonight, oh!

[Verse 2: Calum]
Woke up with a strange tattoo
Not sure how I got it
Not a dollar in my pocket
And it kinda looks just like you
Mixed with Zach Galifianakis
[Pre-Chorus: Calum, Luke]
La, la, la, whatever
La, la, la, it doesn't matter
La, la, la, oh, well
La, la, la

[Chorus: Luke]
We're going at it tonight, tonight
There's a party on the rooftop top of the world
Tonight, tonight, and we're dancing on the edge of the Hollywood sign
I don't know if I'll make it, but watch how good I'll fake it
It's alright, alright, tonight, tonight

[Post-Chorus: Luke & Calum]
You got me singing like, whoa
C'mon! Oh, it doesn't matter, whoa
Everybody now, oh!

[Refrain: Michael, Calum]
Just don't stop, let's keep the beat pumpin'
Keep the beat up, let's drop the beat down
It's my party, dance if I want to
We can get crazy, let it all out
It's my party, dance if I want to
We can get crazy, let it all out
It's my party, dance if I want to
We can get crazy, let it all out
[Bridge: Michael, Calum]
It's you and me, and we're runnin' this town
And it's me and you, and we're shakin' the ground
And ain't nobody going to tell us to go
'Cause this is our show, everybody!

[Chorus: Luke, Luke & Michael, Luke & Calum]
We're going at it tonight, tonight
There's a party on the rooftop-top of the world
Tonight, tonight
And we're dancing on the edge of the Hollywood sign
I don't know if I'll make it, but watch how good I'll fake it
It's alright, alright, tonight, tonight

[Post-Chorus: Luke]
Let me hear you sing!
Oh, oh, oh! Yeah
Oh, oh, oh!
Oh, oh, oh!
