Andrea had a very special dance with some very  close family and friends at her wedding. Her father passed away so her brother  recored "butterfly kisses" and she danced with with all of them during her  Father and Daughter dance. it was a truly touching moment not a dry eye in the  house. Her dad, Mark, died earlier in the year from pancreatic cancer. Andrea's  first dance is with Mark's father, followed by her brother Luke, then brother  Nick and finally her new father-in-law Scott.
