Maybe you are not a fan of the Chicken Dance. Although a traditional wedding song, never feel pressured into doing it at yours.
Maybe there are songs that you can not live without hearing. Make certain to write those down as well. Talk to your DJ about the list. Also make sure that your planner has a copy as well. That way of there is a song request from a guest and it is on the no play list, it will not be played.
One song I always recommend though is "The Time Warp". It is one of those quirky songs and dances that almost everyone knows. And enjoys.
It's just a jump to the left. . . .
