The tabs up already were helpful but I thought they were a little off. This is 
just my take on the song. 

The song is played with a capo on the 7th fret and all the chords are relative to that.

Intro:
e|-0--0-0-0---------|
B|-1--1-1-1---------|
G|-0--0-0-0---------| x2
D|-2--2-2-2-0h2-0h2-|
A|-3--3-3-3---------|
E|------------------|

C
If you should be 

Am
the last Autumn leaf 

F                     C
hanging from the tree,


C
I'll still be here 

Am
waiting on the breeze 

F                       C
to bring you down to me.



Em                 F
And if it takes forever,

Em            Am
Forever it'll be...

Em                 F
And if it takes forever

G
Forever it'll be..


Bridge:

C
And if you should be 

Am
the last seed in Spring 

F                    C
to venture out a leaf


C
I'll still be here 

Am
waiting on the rain 

F                         C
to warm your heart for me.



Em                 F
And if it takes forever,

Em            Am
Forever it'll be...

Em                 F
And if it takes forever,

G
Forever it'll be...
