Calvin Harris – Summer chords

These are the chords to Summer by Calvin Harris. 

                       C     G     DWhen I met you in the summer
                Am     Bm     CTo my heartbeat sound
            C     G     DWe fell in love
                     Am     Bm     CAs the leaves turned brown

               C     G     D    We could be together baby
                      Am     Bm     CAs long as skies are blue
             C      G     DYou act so innocent now
                Am     Bm     CBut you lied so soon
When I met you in the summer


Then it just repeats. The rhythm is something like two strums on the C and G, then 
one strum on the D, two strums on the Am and Bm and one on the C.
