This is my first tab uploaded at harptabs.com
It is certainly not my favorite song, but very easy to play for beginners (like me).

(REFRAIN:)

      C
4   -4 5   5   5
I'm a big big girl

     G/B
5 -5 -4  -4  -4
in a big big world

           F/A                  C     G
-4   -4  5  4   4   4    4  -4   5 -4 5
It's not a big big thing if you leave me

      C
4  -4 5   5  5
but I do, do feel

       G/B
5   -5 -4  -4  -4
that I do, do will

         F/A
-4   5   5 -4 4
miss you much

C          G   C
-5   5   -4 5
miss you much...

(END REFRAIN)

C             G/B
5 5   5   -4  -4    5     5    4
I can see the first leafs fall-ing

F/A         C             G
4    4   4  5   -4  -4  4
it's all so yel-low and nice

Am           G
4    -4 -4 4  -4   -4  4 -4 5 -4 5
It's so ve-ry cold out-side

F                C          G
-4   -4  -4  4   5   -4   4   5
like the way I'm feel-ing inside

REFRAIN

(Outside it's now raining
and tears are falling from my eyes    (Like first couplet)
Why did it have to happen?
Why did it all have to end?)

REFRAIN

Dm            G
-5 -5  5    5    -4 4    -4
I have your arms a-round me

Am          F
5    -4   -4 4
warm like fire

    Dm               G
5   -5  -5 6 -5  5  5  -4  5
but when I o-pen my eyes

         C
4      4
you're gone...

REFRAIN

2x, ending:

D  A       D
-5   -4  -4
miss you much...
