I play this on piano and it sounds completely right, so I thought I would post it 
up for others to use, enjoy!

Intro:  C    G     Am     F    X2

Verse 1:
           C                         G
I picked a wishing weed beneath your mother's tree
       Am                  F
And i asked it to bring you back to me
       C                 G
Then a dragonfly took it to the sky 
       Am                       F
And it rode on the wind until it caught your eye

Chorus:
    
    C                   G         Am     F
And I’m never gonna get over -- you
 C                         G               Am    F
Not cause i can't, cause i don't --- want   to
 C                G            Am          F
I’m gonna get you back if it's the only thing i do
  F                 G     C
I’m never gonna get over you…

Verse 2: 
           C                         G
I took the secret path to where i saw you last
       Am                  F
And a sparrow dropped a letter to me as it passed
       C                 G
There was a simple sketch of a heart in red
       Am                       F
And it broke me when i opened it cause all it said was:

Chorus: 
    C                   G         Am     F
And I’m never gonna get over -- you
 C                         G               Am    F
Not cause i can't, cause i don't --- want   to
 C                G            Am          F
I’m gonna get you back if it's the only thing i do
  F                 G     C
I’m never gonna get over you…

Bridge:  
   C
Of all the lovers found and lost
     G
And never seen again
 F
You’re the only one that runs
  G                     Gsus4
Repeating through my head...
