This song is tuned a half step down.

    E5                A5
The sun will come out tomorrow
E5                              B5
Bet your bottom dollar that tommorrow
            A5  B5
there'll be sunshine


     E5             A5
Just thinkin' about tomorrow
E5                              B5
Bet your bottom dollar that tommorrow
            A5  B5
there'll be sunshine
   E5
sunshine


E5            B5                     A5 
Now I try to sort out my scattered life
E5      B5           A5
Lying awake on the floor
E5       B5              A5
Staring at the ceiling light
E5           B5      A5
Until I can see no more...


The rest of the song is just the same E B A riff.  There are two little fills in the verses.
