Mother-Son dance for my mom and Autistic brother?

I am getting married next fall and my sister and I thought it would be a nice thing to do to give my mom and brother a Mother-Son dance at my wedding. She will never get the opportunity otherwise and he is the only son in our family. I would love to end the song with a transition into the chicken dance (my brother's favorite!) to lighten the mood if its really emotional (which I am sure it will be).

First, what are your thoughts on doing this? And second, any suggestions for a fitting song? Any help is appreciated!!
