                         Am    C    D/F#
When I met you in the summer
                    Am    Em    C*
To my heartbeat sound
             Am    C   D/F#
We fell in love
                      Am   Em     C*
As the leaves turned brown

                   Am    C  D/F#
We could be together baby
                       Am   Em     C*
As long as skies are blue
                     Am    C   D/F#
You act so innocent now
                 Am   Em     C*
But you lied so soon
                Am
When I met you in the summer
