This is a memorable moment. If you don't / can't dance Northwestern Michigan College (check your local college) offers a short class on first dance at a reasonable price. Another option is to enlist the help of a choreographer. You will want to get your DJ's copy of your song, and let the DJ know where you want to start the song.

We had a couple picked out 4 songs and had us build a montage. Now talk about making it your own. Even now, yeas later we still talk about that night.
