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.

          EmI (022000@1)know this pretty rave girl
      CAlways (x32010@1)think about her
             GAnd (320003@1)when she says hi to me
           DButterflies (xx0232@1)go right through me
                     EmAnd (022000@1)When I see her dancing
              CWanna (x32010@1)take a chance 
                GAnd (320003@1)get in a little closer
            DAnd (xx0232@1)maybe get to know her
