[Hook: will.i.am]
Yesterday, yesterday, yesterday
I wanna go back to yesterday
I wanna go back to yesterday
I wanna go back to yesterday
I wanna go back to yesterday
Yesterday

[Verse 1: Taboo, will.i.am and apl.de.ap]
We going back to the front, give them what they want
Back to the past, retro glass
Back to the leader, back to reviews
Take 'em back to the future, take 'em to the true school
Cause we was breaking atoms, live at the barbeque
Now we reminiscing, pumping Audio Two
Listening to n***as, n***as with them attitudes
Apl was a Black Sheep screaming out
"You can get with this or you can get with that"
Smoke emcees, or you could smoke crack
You can sell dope, or you can sell raps
I sell dope raps cause that's where it's at
Now I'm back on the scene, crispy and clean
Hip hop fiend, Source Magazine
World Famous is the Supreme Team
SP-1200 drum machine
Hail to Latifah, she be the queen
DMC and Run be the kings
King of Rock! My n***a Ice-T killed a cop
And we be to rap what key be to lock
[Interlude: will.i.am and apl.de.ap]
I'm cool like that, I'm cool like that
I move like that because I'm smooth like that
I rap like that because I'm phat like that
I rock like that because I got it like that
And I'm ill like that, skilled like that
Phil-i-ppines, cause I feel like that
I'm real like that, yes, I'm chill like that
You gots to chill

[Verse 2: will.i.am, Taboo and apl.de.ap]
I got pounds and pounds of peas, you know
I'm not Large Professor but I'm an extra pro
Punks jump up to punk rock'n'roll
The Master P-nut is a pistachio
The Peas peak past the pinnacle plateau
Posses a fresh Porsche, I don't push Peugeot
Packing out paper in a pass I was pulled
Get paid to rock mics and used to call the show
Here we go, yo, here we go, yo
Check the flow yo, 'cause this retro
It's my classic mani-fucking-festo
Lyrically, I'm magic, fucking presto
Insuring hip-hop like gecko
Making sure it won't stop, baby, heck no
That's a what, that's a what, the scenario
Reminiscing while I listen to the stereo
[Interlude: will.i.am]
I reminisce, I reminisce
I reminisce, I reminisce
When it's sounding like this
Downtown, go round

[Hook: will.i.am]
I wanna go back to yesterday
I wanna go back to yesterday
I wanna go back to rappable
Cause oh baby, I like it raw
Yeah baby, I like it raw
Oh baby I like it raw
Yeah baby, I like it raw

[Verse 3: will.i.am, apl.de.ap and Taboo]
Shimmy shimmy ya, shimmy yam, shimmy yay
Comment allez-vous, parlez vous francais?
Adiós, motherfuckers, bon voyage
Home of the liquid flows and Liquid Swords
Black-Eyed Killer Peas on the swarm
Coming to your college and disco dorm
Y'all can't touch my skills
I can switch it up, Das EFX, and get iggity-iggity-ill
Yiggity-yes, rapper, my style is unique
Iggity-ice on my teeth so it's cold when I speak
Word to mom, I'm in my own world
Galaxy rays! Powerful
[Hook: will.i.am]
I wanna go back to yesterday
I wanna go back to yesterday
I wanna go back to yesterday

[Verse 4: Taboo, apl.de.ap and will.i.am]
So I can hit you with the bass, how low can you go?
I get lower than a midget doing limbo
I got shit that you haven't heard a while ago
'88-'92 the style'll go
Way back, rocking on the A-track
Memorex, TDK, all of that
Throwback before all the Nazareth
Willy is his name and the boy's coming
Straight Outta L.A! A crazy motherfucker named Willy
I'm so cold, my flow stay chilly
I got a laser aimed at them haters
And I'm cutting motherfuckers with my razor
You too, boy, if you fuck with me
I'ma dice you up, slice you up quickly
I signed to Ruthless when Dre dropped "Dre Day"
That's why I do this, to bring you back to yesterday
(Yesterday, yesterday, yesterday)
Tiger style
There's no place to hide as I step inside the room
Dr. Doom, prepare for the boom
Bam, I slam, aw, man
You fucking with will.i.am!
Cause I'm torching and scorching, my style is awesome
Cracking motherfuckers' skulls like it's porcelain
Aiyyo, let's save hip hop from Dr. Kevorkian
Bring it right here, right back to its origin
Aiyyo, I'ma hop in my motherfucking DeLorean
So I can go back and fucking perform again
Aiyyo, I did some windmills on some fucking linoleum
MC mic controlling them, I was like
(Woop-woop!) I was steady policing them
Killing emcees, I was straight deceasing them
(Woop-woop!) Compute-deleting them 'til them n***as don't exist
Because Black Eyes Peas is hard as hell!
Battle anybody, I don't care if you tell
I excel! They all fail!
I told them motherfuckers I'mma take them—

[Outro: will.i.am]
Back to yesterday
I'm taking you back to yesterday
I'm taking you back to yesterday
I'm taking you back to yesterday
I took you back to yesterday
I took you back to yesterday
I took you back to yesterday
I took you back to yesterday
And now I'm taking you to the future
I'm taking you to the future
I'm taking you to the future
I'm taking you to the future
I'm taking you to the future
Taking you to the future
Take you to the future
Take you to the future
Future, future, future, future, future...
