Activity for Katie

I have some songs in mind but was wondering what other couples are going to use for when their bridal party is announced at the reception as well as what the parents and grandparents are walking down at the ceremony.

Okay so it's that time for my MOH to plan the bachelorette I will be helping her but I also need some help. My MOH (my cousin) is 20 and won't be 21 by my trip. So with that being said I have 1 underage and 1 that is pregnant. I need help for ideas...
