Standard Tuning: E A D G B E  
F          G           Am
 Love of my life, my soulmate 
F  G                   Am
   You're my best friend 
F       G          Am
 Part of me like breathing 
F            G      Am
 Now half of me is left 
             F       G     Am
I Don't know anything at all 
 
      F        G      Am
Who am I to say you love me 
 
            F        G    Am
I don't know anything at all 
          F        G      Am
And who am I to say you need me 
*From here on just repeat above*...
Color me blue I'm lost in you
 Don't know why I'm still waiting 
Many moons have come and gone 
Don't know why I'm still searching 
Don't know anything at all
 And who am I to say you love me
 I don't know anything at all 
And who am I to say you need me 
Hmmm hmmm mmm Uhhh oohhh 
aahhh Hooo aahhh ohh ohhh 
Now you're a song I love to sing 
Never thought it feels so free 
Now I know what's meant to be 
And that's okay with me 
But who am I to say you love me 
And who am I to say you need me 
And who am I to say you love me 
Mmmm hmmm 
I don't know anything at all 
And who am I to say you love me 
I don't know anything at all 
And who am I to say you need me 
I don't know anything at all 
I don't know anything at all 
I don't know anything at all 
I don't know anything at all
