My husband and I are doing a vow renewal for our 10 year anniversary. We are going to do a sand ceremony in which we pour sand into a special frame. (www.theforeverframe.com) For us it is representing our continued love and commitment to each other while maintaining our individuality. The song we are having is Songbird by Fleetwood Mac. http://www.youtube.com/watch?v=MpjMjLIp1Xk
