[Intro: Jessie J & Robin Thicke, (Jessie J)]
Calling all hearts (Wooo)
To the dancefloor, tonight
Let love start (Let love start)
Oooooh, hey!

[Pre-Chorus: DJ Cassidy]
Oh!
Calling all party people in the place to be
We gonna celebrate tonight
And rock out with the family
Here we go!

[Chorus: Jessie J & Robin Thicke]
Calling all hearts, to the dance floor
Tonight, let love start
On the dance floor, tonight
Listen up!

[Verse 1: Jessie J]
I got a feeling everybody needs a reason to shout
Leave all your problems and your drama at the door and get down
This is where we all unite
(If we get it right, we gonna light up the sky)
At this place, in this time
(We gotta let go, 'cause it's alright)
[Chorus: Jessie J & Robin Thicke, (Jessie J)]
Calling all hearts, to the dance floor (To the dance floor)
Tonight, let love start
On the dance floor, tonight

[Verse 2: Robin Thicke & (Jessie J)]
Tonight
Go a little harder with your partner
Heat it up in this place
(Heat it up, heat it up, heat it up, heat it up, heat it up, heat it up, in the place)
It's ok to mingle if you're single, put a smile on your face
Oh yeah, baby
This is where we all unite
We gonna groove
We gonna move into the night
At this place and time, yeah
(You gotta let go cause it's alright)

[Chorus: Jessie J & Robin Thicke]
Calling all hearts, to the dance floor (Right to the dance floor)
Tonight, let love start (Let love start, let love start)
On the dance floor, tonight
Come on!

[Breakdown: Jessie J & Robin Thicke, (Jessie J)]
If they're beating tonight
Then I'm calling all hearts, you can call in all hearts, yeah
A celebration of love (A celebration of love)
So I'm calling all hearts, you can call in all hearts, yeah
[Bridge: Jessie J & Robin Thicke]
A little bit louder
A one, two...a one two
One, two, three, go
Shake it, shake it down tonight, that's right
Shake it down, shake it down, that's right
Shake it, shake it down tonight, that's right
Dance a little bit more (Just dance a little bit more)
Come all night (Come together, hey)
Move a little bit more
Come now, oh yeah

[Chorus - Jessie J & Robin Thicke]
Calling all hearts, to the dance floor (Tonight)
Let love start (Let it start, you gotta let it start)
On the dance floor tonight
Calling all hearts
I'm calling everybody, I'm calling everyone
I'm calling everybody, get your butt on the floor!
Tonight is the night
Tonight is the night
Tonight is the night
I'm calling all hearts, I'm calling all hearts
I'm calling all hearts, I'm calling all hearts
I'm calling all hearts, I'm calling all hearts
I want everybody on the dancefloor
Come on
We're gonna rock tonight
(Calling all hearts)
Until we brought daylight (?)
(Damn Jessie)
Calling all hearts, hearts, hearts
We go on and on...
You won us with that Cassie!
Calling all hearts
Until we get dark (?)
Calling all hearts...
