When Joe was planning for her wedding to Martin, all she wanted was to have her son Alex dance at her wedding. The problem is, 13-year-old Alex has severe Cerebral Palsy and dancing wasn't possible. That was until Martin devised a plan and spent weeks creating a special harness so that he could help Alex dance. When you see the look on this bride's face when her son comes out to dance you'll be reaching for the tissues. What an incredible wedding surprise.
