Bb7M  Bº   Eb7M   Eb7M
I waited 'til I saw the sun 
Gm7          C7    Eb7M  Bb7M 
I don't know why I didn't come 
Bb7M  Bº   Eb7M   Ebm6
I left you by the house of fun 
Gm7          C7    Eb7M  Bb7M 
I don't know why I didn't come 
Gm7          C7    Eb7M  Bbm6

Bb7M  Bº   Eb7M   Ebm6
When I saw the break of day 
Gm7          C7    Eb7M  Bb7M 
I wished that I could fly away 
Bb7M  Bº   Eb7M   Ebm6
Instead of kneeling in the sand 
Gm7          C7    Ebm6  Bb7M 
Catching teardrops in my hand 

Refrão:

But you'll be on my mind

 Fo  re   ver 

Bb7M  Bº   Eb7M   Ebm6
Out across the endless sea 
Gm7          C7    Eb7M  Bb7M 
I would die in ecstasy 
Bb7M  Bº   Eb7M   Ebm6
But I'll be a bag of bones 
Gm7          C7    Ebm6  Bb7M 
Driving down the road along 

Gm7        C7(13)         F  F7
My heart is drenched in wine 
Gm7     C7(13)  
But you'll be on my mind

Bb7M  Bº   Eb7M   Ebm6
Something has to make you run 
Gm7          C7    Eb7M  Bb7M 
I don't know why I didn't come 
Bb7M  Bº   Eb7M   Ebm6
I feel as empty as a drum

obs: alguns acordes podem estar diferentes do original mas todos 
possuem exatamente a 
mesma função... ( preparação V7, resolução I6/9 etc ..)tirei essa 
música em uma hora para corrigir o primeiro cara que mandou, pois sua
 cifragem estava completamente equivocada.
