You can change your life (If you wanna)
You can change your clothes (If you wanna)
If you change your mind
Well, that's the way it goes

But I'm gonna keep your jeans
And your old black hat ('Cause I wanna)
They look good on me
Your never gonna get them back
At least not today, not today, not today,
Cause...

If it's over let it go and,
Come tomorrow it will seem,
So-o Yesterday So-o Yesterday,
I'm just a bird that's already flown away

Laugh it off
Let it go and
When you wake up it will seem
So-o yesterday
So-o yesterday
Haven't you heard that I'm gonna be oka-ay

You can say you're bored (If you wanna)
You can act real tough (If you wanna)
You could say you're torn
But I've heard enough

Thank you
You've made my mind up for me
When you started to ignore me
Do you see a single tear
It isn't gonna happen here
At least not today, not today
Not today, 'cause

If it's over let it go and
Come tomorrow it will seem
So-o yesterday
So-o yesterday
I'm just a bird
That's already flown away

Laugh it off
Let it go and
When you wake up it will seem
So-o yesterday
So-o yesterday
Haven't you heard that I'm gonna be oka-ay

If you're over me, I'm already over you
If it's all been done, What is left to do
How can you hang up, If the line is dead
If you wanna walk, I'm a step ahead
If you're movin' on, I'm already gone
If the light is off, Then it isn't o-on
At least not today,Not today
Not today, 'cause

If it's over let it go and
Come tomorrow it will seem So-o yesterday ,So-o yesterday
I'm just a bird
That's already flown away

Laugh it off
Let it go and
When you wake up it will seem So-o yesterday,So-o yesterday
Haven't you heard you're so-o (yesterday)
So-o yesterday
I'm just a bird
That's already flown away
Laugh it off
Let it go and
When you wake up it will seem So-o yesterday,So-o yesterday

Haven't you heard that I'm gonna be okay?
