Song For Bridesmaids To Walk To

I need a song for my bridesmaids to walk to down the aisle to. It will be in a church so needs to be reasonable but I am getting so bored of all that piano stuff. . It will need to be short or sound good when cropped. The 3 girls are my very closest friends that have known me all my life (as short as it is). I want the song to not only reflect me and the groom, but them. Any suggestions? Much appreciated.
