That's the intro, although i can't play it jet. but i copied it from someone else, 
he or she didn't know the chords.
And I'm not sure if they're right, but let's give it a try.

                AM                         C
I wanna Shout it from the rooftop
            G                D
I'm in love I'm in love
                AM                          C
And the favourite thing to do
                         G                               D
Is thinking of you, is thinking of you


and so on.
i hope it's okay?
