Good afternoon. I am excited that I will be getting married soon

But I really could use your help or creativity. I am going to do a surprise mother/daughter and also a surprise grandfather/granddaughter dance at my wedding. I want to write a speech or a note to maybe have the dj announced (I don't mind speaking instead of the dj.) that I will be doing a surprise dance for my mom and grandpa. Anyone know what I or the dj could say to surprise them to doing these dances with me. Thank you :-)
