This is of course is a very rough first interpretation. I own a guitar, not a 
ukelele, so you would put a capo on the sixth fret.

G          D 
If I go before I say
               Em
To everyone in my ballet
                 C
Let me take this chance
                     G
To thank you for the dance

                D 
If I run out of songs to sing
                      Em
To take your mind off everything
      C            
Just smile, see the wild with the 
Am
Sun on your face and
G                     D                      Em
Remember the place we met, take a breath and soon
             C
I bet you?ll see

Without you I would never be me
Am                        D
You are the leaves of my family tree

G    D- Em- C    
Sing together
G                        D
If you knew me from the very start
      Em                    C
Or we met last week at the grocery mart
     G    D- Em- C
Just sing together
         Am                      D
It?s the least that I can do, my final gift to you 

G-D-Em-C (x3) Am-D
oooh (x3)     oooh 

G                D
When I pass the pearly gate
                 Em
I will find some real estate
                    C
Where we can settle down
                       G
And watch the world go round
                        D
We?ll send down all the love we got
                        Em
And let them know we?ve got a spot
            C
For them to be, and it?s so free

    Am            
The Sun on your face, and
G                     D                      Em
Remember the place we met, take a breath and soon
             C
I bet you?ll see
                             Am
Without you I would never be me 
                          D
You are the leaves of my family tree

G    D- Em- C
Sing together
G                       D
If you knew me from the very start
   Em                 C
Or not at all, you?re still a part,
     G    D- Em- C
Just sing together
          Am 
It?s the least that I can do
    D
My final gift to you

G-D-Em-C (x3) Am-D
oooh (x3)     oooh 


And that's how it ends. It's not perfect, feel free to make corrections, but it's 
the best I could come up with. Remember to sing together!
