Everyday, down the street
Where we live
We walk, we talk
Watching each day go by

It may not seem much
From the outside in
But there you are
It doesn't say who we are
And baby

I wouldn't change a thing
You couldn't change a single thing
Without it affecting everything
I wouldn't change a thing

Every week, afternoons
Give or take
We hone our trade
Taping the songs we've made

And at night
When we turn out the light
Next to me
You're watching
A late night show
And I go

I wouldn't change a thing
You couldn't change a single thing
Without it affecting everything
I wouldn't change a thing
