I noticed the other tabs had a few lyrics wrong, and possibly a couple of chords. 
I've also but the tapping bit in for one of the chorus/verses. If you think it 
gets repetitive, just single strum the chords, it sounds quite nice.
This my first tab, and I think it's relatively good. Comments and constructive criticism welcome.

Capo 4:

G                         C                 G
Good morning sunshine, I hope that you're well
Honey I missed you, last night when night fell
You should know, sunshine, you brighten my day
The world gets so dark, love, when you go away

          Em
They say absence makes the heart grow fonder
    C                    D
But I can't help but wonder

        G         F      C
If the darkness came tomorrow,
         G        C     D
Could I keep you in my mind?
          G        F        C
Will you rise and let me follow
               G
Just for the chance
     C             G
To stand in your light

Good morning sunshine, I'm glad you're still here
My darling it's hard when my friends can't be near
Till I can be there to show them I'm true
I hope what they're seeing is as bright as you

          Em
They say absence makes the heart grow fonder
    C                    D
But I can't help but wonder

        G         F      C
If the darkness came tomorrow,
         G        C     D
Could I keep you in my mind?
          G        F        C
Will you rise and let me follow
               G
Just for the chance
     C             G
To stand in your light

Instrumental (G Em D x2)

        G         F      C
If the darkness came tomorrow,
         G        C     D
Could I keep you in my mind?
          G        F        C
Will you rise and let me follow
               G
Just for the chance
     C             G
To stand in your light

               G
Just for the chance
     C             G (Sustain)
To stand in your light

(No chord)                 (Drums (tapping pattern on guitar, listen to track for some ideas))
Good morning sunshine, I wish for your heart
There's no point pretending that you won't burn out
But you're still a symbol to all that you meet
                                 (stop tapping)
'Coz you keep on shining, you're extraordinary

(More tapping (or single strum of each chord))
If the darkness came tomorrow,
Could I keep you in my mind?
Will you rise and let me follow
Just for the chance
To stand in your light

        G         F      C
If the darkness came tomorrow,
         G        C     D
Could I keep you in my mind?
          G        F        C
Will you rise and let me follow
               G
Just for the chance
     C             G
To stand in your light

G (Sustain)              C    B
Good morning sunshine!
