I Need Your Help!!!

I need your help ladies.....FH and I are trying to think of songs for our montage at the wedding....
We need one for our dating pictures and we need one to play during the 'In Memory Of' montage for his mom that will be showing pictures of FH mother during the time he would have been dancing with his mom....
I was thinking of the song Perfect Fan by The Backstreet Boys for the In Memory Of part....
What do you ladies think?
Can any of you come up with any suggestions?
FH and I have been racking our brains for a week now....
Hope you ladies can help....
Thanks
