song for our wedding in memory of his mom?

no don't cut the father daughter dance, keep in mind it's your dad's only chance to have a spotlight dance with you in front of all the guests and don't deprive him of that. instead of a slow sad song, maybe the groom can pick a fast oldies song his parents loved and everyone can boogie to that and celebrate them instead of having a morose weepy moment in their honor.

You do something quietly with just family, so as not to intrude your personal grief onto all the people who have kindly come to help you celebrate a happy occaision. Your guests are there for your WEDDING, not for the ups and downs of your whole life. This is not disrespect to your mother, and not trivialization of your deep sadness, but you should keep in mind all day that your primary goal on that day should be to live up to your guests' expectations and provide them with a joyous celebration. Keep in mind that when 'memorials' are allowed to intrude into a wedding, many guests will be thinking "Isn't she getting enough attention as The Bride? Now she has to be Little Miss Mournful too?"

I have never heard of the mother son dance before only the father daughter dance. I would keep any dedications and stuff to the wedding and make the reception more relaxed. Your father might be hurt if you leave him out.

A dedication song to his mother during the ceremony could be "Wind beneath my wings" or Because you loved me by Celine Dion

These are common dedication songs. Maybe play a slideshow of him and his mom during the time in ceremony where the mother of groom is supposed to walk.

Please don't do this. You have invited people to a fun and festive celebration of a happy event -- your marriage. It isn't nice to pull a 'bait and switch' and insist that these festive minded party goers switch gears into mourning and grieving. That belongs at some other event where the deceased is the center of attention, not at your wedding where bride and groom are the center of attention.

Your idea of modifying the first dance, second dance part of the festivities to match the reality that not every pair of newlyweds comes with 2 pairs of parents -- that is the right idea.

Very hard to say... I have lost both My parents too. heres a couple of ideas . His mums favorite, dads favorite..... his parents wedding dance song, ??? ........or ....sad.. but meaningful... slow waltz.. Danny boy or Amazing grace

WEST LIFE - You Raise Me Up! (youtube doesn't show it anymore)

I think it is a beautiful thing to do, definitely let him have that moment.

What about Train's "When I look to the sky" it has an upbeat tone to it...
