Need help with pre-ceremony slideshow...?

I am making a dvd slideshow of pictures of my fiance and I from when we were babies all the way up to us meeting, and our engagement pictures. I need a song to set them to but I am having trouble thinking of anything suitable. I think it would be easier to pick out music if I showed his pictures and then mine then our together pictures but I don't want it to drag out forever so I would rather show them at the same time, like our first baby pics, Halloween, Christmases, high school sports, graduation etc. Only thing I can think of is the Brad Paisley song "When Two People Fell in Love" but I'm not a big fan of the song. Thank you for your help!
