Charlie Mcdonnell – Birthday Song chords

It's very easy to play,
With Ukulele, you just bar across on the third fret then put your fingers on the 4th on
E and 5th on G to form the first note - Ab. The second chord you play is just moving all
your fingers down a fret to a G, then for the last note, I think it's some kind of cm? 
Let's call it a cm for the sake of this. But it's basically just the first chord without
your finger on the E.
In other terms:

[Ab]                  [G]                [Cm]This is a song that I wrote you for your birthday
[Ab]                  [G]                [Cm]Because I couldn't be bothered to buy you anything
[Ab]                      [G]And I know that you might think that
             [Cm]               [G]Writing this song required more effort
           [Ab]    [G]        [Cm]Than going out and buying you something

(still Cm)But I can promise that it didn't
[Ab]         [G]                   [Cm]I'm not even going to include your name in this song
[Ab]                  [G]           [Cm]Because that way I can use it on somebody else
[Ab]                 [G]             [Cm]          [G]And if you listen closely then you might be able to tell
       [Ab]          [G]          [Cm]That I only bothered using three chords
                                       [G]I guess that just shows you how much I care

[Ab]  [G]      [Cm]        [G]Happy birthday insert name here
[Ab]               [G]            [Cm]Congratulations on living another year
[Ab] [G]      [Cm]          [G]Only joking I did get you something
    [Ab] [G]   [Cm]And it's right here
