[Chorus: Taboo, will.i.am & Fergie]
Yo what's up? What's going down?
Let's start it up, It's not too late
It's not too late to start it up
Party on for you...
Yo what's up? (yo what's up?) What's going down? (is going down)
Let's start it up (start it up) It's not too late (it's not too late)
It's not too late (it's not too late) To start it up
Party on for you...

[Verse 1: will.i.am]
Buckle up, here comes the shakedown
We gon' turn it up, listen to the bass pound
You got to react, high to the high hat
Bounce to the boom bap, we gon' make your soul tap
When we came through y'all was all mellow, mo
We motivated a marsh pit like heavy metal
Rock crowds from punk rock to soul
And bring funk to monks and aunts and uncles
(What you getting good?) We da real mother funkers
Funk what you thunk we the ones that a funk up
Cadillac trunk filled with B-E-P bumpers
Dumping out concrete like cement thumpers

[Chorus: Taboo, will.i.am & Fergie]
Yo what's up? What's going down?
Let's start it up, It's not too late
It's not too late to start it up
Party on for you...
Yo what's up? (yo what's up?) What's going down? (is going down)
Let's start it up (start it up) It's not too late (it's not too late)
It's not too late (it's not too late) To start it up
Party on for you...
[Verse 2: Taboo]
Rock hard, hard rock, bombard your whole block
Reinforce my fleet, the funk is non-stop
Dance y'all, dance hard, I'm back with weekends
Tied a place in your face with shit thats pleasing
Yeah, we be the main source serving up the main course
Don't stop, planet rock, light source, sonic force
Bang-bang, boogie-boogie up jump the jumpstart
Ignite to take flight we rocked ya depart (where?)
To the third part (what?) it's a trilogy (huh?)
[Robotic voice]
(What you didn't know) Ay yo we bring the bumps
Bumps for your trunk and we making the thump-funk

[Chorus: Taboo, will.i.am & Fergie]
Yo what's up? What's going down?
Let's start it up, It's not too late
It's not too late to start it up
Party on for you...
Yo what's up? (yo what's up?) What's going down? (is going down)
Let's start it up (start it up) It's not too late (it's not too late)
It's not too late (it's not too late) To start it up
Party on for you...

[Verse 3: apl.de.ap]
Yo we up again, listen up it's the Peas with the sound
We's about the break out, shake the whole Earth now
Bass down up and loud whenever we get (down)
Set it off in your town. together we all pound
Whoever you are we gonna make you do it
Whatever you do it just stop and dance to this
This is the diggy-diggy-diggy-diggy rock-rock
This is the diggy-diggy-diggy-diggy crew-crew
