Capo 3
Don't Worry Be Happy - Guy Sebastian

      (G) 
I was driving, driving, driving down the 101
        (Em)
Singing 'California Dreams' at the top of my lungs
    (C)          (D)
Unaware, not a care
                  (G)
And then he appeared
               (G)
Thought he was winding down his window just to say 'hello'
       (Em)
But he started cussing at me, saying I'm going to slow
        (C)           (D)
Then he yelled "Go to Hell"
                     (G)
then flipped me the bird
       (Am)
Is it really that bad?
Really that bad
                  (C)
I don't think it's really that bad
Come on, get with it

      (G) 
If you only think of things that you haven't got
           (Em)
You could have it all and still never have enough
         (C)                      (D)
So don't worry (don't worry), be happy (be happy)

             (G)
And if you're trying to make a move
                              (Em)
But you're stuck in mud, under water

And you don't know which way's up
            (C)                    (D)
Yeah, don't worry (don't worry), be happy (be happy)

        (G)
Another day, another plane, another interview
    (Em)
Just trying hard to get thru my list of things to do
           (C)                  (D)
What's the use, might fake the flu
             (G)
Coz I've had enough
            (G)
That's it - screw the low carbs, where's my KFC?
             (Em)
Ain't gonna think about the bills or the GFC
        (C)            (D)
Life is short - live it up
               (G)
Coz we live it once

(Am)
Is it really that bad?
Really that bad
                  (C)

Come on, get with it

                       (C)
We only get to live it once

So live and love
                       (G)
And give it all you've got

Yeah life is short
                (D)
We only live it once

So live it up
