This song is awesome! Sorry if it is confusing. If you have hard time reading it, or
whatever, then listen closely to the song. I got this tab off a video of a professional
guitarist, BUT it is very hard to understand what he is trying to teach us.

   I'm very certain that this is 99% accurate
    *-One Strum
   NOTE--- Where it says (No Chords), if you listen to the song, that part doesn't have
any strumming in it, just claps and drums.

Then you repeat everything :) The bridge is a simple E chord!



Lyrics:

Hello, hello
I know it's been awhile, but, baby
I got something
That I really wanna let you know
Yeah
Something that I wanna let you know

You say
You say to everybody
That you hate me
Couldn't blame you
Cause I know I left you all alone
Yeah
I know that I left you all alone

Yeah

Now I'm back at your door
You're looking at me, unsure
I should've seen it before
You're all I think about
Baby

I was so stupid
For letting you go
But I-I-I know
You're still the one
You might have moved on
But, girl, you should know
That I-I-I know
You're still the one
I know I'm saying too much
But I will never give up
I was so stupid
For letting you go
But I-I-I know
You're still the one
I-I-I know
You're still the one

Hello, hello
I'm really hoping you'll forgive me
I keep talking, begging
Tell me what I wanna hear
Yeah
Girl, just tell me what I wanna hear

I tried and tried
To start again and find somebody
But I remember all the times
And all the words we said
Yeah
I can't get it out of my head

Yeah

Now I'm back at your door
You're looking at me, unsure
I should've seen it before
You're all I think about
Baby

I was so stupid
For letting you go
But I-I-I know
You're still the one
You might have moved on
But, girl, you should know
That I-I-I know
You're still the one
I know I'm saying too much
But I will never give up
I was so stupid
For letting you go
But I-I-I know
You're still the one

I-I-I know

Hey
You
You're still the one
Hey
You
You're still the one
Hey
You
You're still the one
Hey
You
You're still the one

I know I'm saying too much
But I will never give up
I was so stupid
For letting you go
But I-I-I know
You're still the one
I-I-I know
You're still the one
