VERSE 1:

E         E7
Ever since,
       A              E
I first laid eyes on you,
E                B7 
I don't know what, 
                     E
I don't know what to do,
E                E7 A
I must be a fool, 
               E
To go out and chase you,
                     B7
But that's just what,
                      E
That's just what I'll do.

CHORUS 1:

E                    E7
And I am, chasing a ghost.
A           E
And I am, a fool.

E E7
Mmmmm...
A E E7 E
Ooooh...
B E
Ahhhh...

VERSE 2:

E         E7
Ever since,
                  A         E
You packed up and walked away,
E                B7
Well all my skies,
              E
Have all turned grey.

CHORUS 2 (OUTRO):

E                    E7
And I am, chasing a ghost.
A           E
And I am, a fool.
                  E
And I am, fallin, fallin for you,
                                      E
Ever since, I first laid eyes on you.



(This is my first tab and I had a tough time 
figuring out the precise chord progression 
throughout but specifically during the "Ooooh..." 
part and the last 2 lines of the song. Any 
feedback would be greatly appreciated!)
