This is my first tab, so enjoy. I am using a Capo on the 5th fret, 
and the chords that you see are referring to the chord shapes, rather 
than the names (since the guitar has a capo on it). There are a couple of 
nuances done with some of the chords, like the D, the A and the Gm but they 
are relatively easy to figure out. 

[Verse 1]

  C                   C7
I know (I know) you belong
   F        Fm
To somebody new
    C
But tonight
    G         C     G
You belong to me
  C                        C7
Although (although) we're apart
         F          Fm
You're a part of my heart

[Chorus]

    C
But tonight
    G         C     G
You belong to me

[Verse 2]

     Fm
Wait down by the stream 

How sweet it will seem
     C             D
Once more just to dream in 
    G
The moonlight
           C
My honey I know
          C7
With the dawn 
         F       Fm
That you will be gone

[Chorus]

    C
But tonight 
    G         C    G
You belong to me
    C
But tonight 
    G
You belong
   C
To me
