I posted this in music section but realize it is more etiquette question. I would like to play my parents wedding song at my wedding and have my parents and my fiancé and I dance with them. Just us two couples on the dance floor because my parents are the idle couple of a loving, lasting marriage. However I don't want to offend my future mother-in-law but it is hard to include her because she is divorced and has been for many years and is single not bringing a date. Should I just not do it or is there a way to not offend mother in law? Anyone ever do this? Plus I know it would mean the world to my parents plus bring up wonderful memories of their wedding day.
