[Intro]
    C
Hooow?
G         Am 
Haaaa-oooo-ow-ow? 
   F               G
Haaaa-ahah-ah-ooow? 

[Verse]
  Am
I can’t believe what you said to me 
      G
Last night when we were alone 
               F
You threw your hands up 
            G
Baby you gave up, you gave up 

I can’t believe how you looked at me 
With your James Dean glossy eyes 
In your tight jeans with your long hair 
And your cigarette stained lies 

[Pre-chorus]
Am        Am/G# (Ab,C,E)      Am/G (G,C,E)   
Could we fix you if you broke? 
              F                     G
And is your punch line just a joke? 

[Chorus]
C     B/G          Am
I’ll never talk again
  G                       F 
Oh boy you’ve left me speechless 
             G
You’ve left me speechless, so speechless 

And I'll never love again 
Oh boy you've left me speechless 
You've left me speechless, so speechless. 

[Verse]

I can’t believe how you slurred at me 
With your half wired broken jaw 
You popped my heart seams 
On my bubble dreams, bubble dreams 

I can’t believe how you looked at me 
With your Johnnie Walker eyes 
He’s gonna get you and after he’s through 
There’s gonna be no love left to rye 

[Pre-chorus]
And I know that it’s complicated 
But I’m a loser in love, so baby 
Raise a glass to mend 
All the broken hearts 
Of all my wrecked up friends 

[chorus]
I’ll never talk again 
Oh boy you’ve left me speechless 
You’ve left me speechless so speechless 

I’ll never love again, 
Oh friend you’ve left me speechless 
You’ve left me speechless, so speechless 

[same chords are chorus]
Hooow? 
Haaaa-oooo-ow-ow? 
Haaaa-ahah-ah-ooow? 

Hooow? 
Haaaa-oooo-ow-ow? 
Haaaa-ahah-ah-ooow? 

[Bridge]
F                           E
And after all the drinks and bars that we’ve been to 
           Am
Would you give it all up? 
          G                  F
Could I give it all up for you? 

And after all the boys and the girls that we’ve been through 
Would you give it all up? 
Could you give it all up? 
If I promised, boy, to you 

[Ending]
C           B/G         Am     F   
That I’ll never talk again 
C         B/G           Am     F
And I’ll never love again 

C     B/G           Am
I’ll never write a song
        Em           F 
Won’t even sing along 
       G
I’ll never love again 

[Normal Chorus chords]
How, How
So speechless, hey hey. 
You left me speechless, so speechless aye aye 

You ever talk again, oh boy why you so speechless? 
You left me speechless, so speechless 

Some men may follow me 
But you choose “death and company” 
Why you so speechless? Oh, oh
