you can mess around with the capo to fit your vocal range better, but this 
sounds right to me.    

intro: Em C G D
and just repeat it all the way through.  for the slow parts just strum each chord once.

          Em
I know this pretty rave girl
      C
Always think about her
             G
And when she says hi to me
           D
Butterflies go right through me
                     Em
And When I see her dancing
              C
Wanna take a chance 
                G
And get in a little closer
            D
And maybe get to know her
