Father/Daughter Song

I am looking for a song to play in our slide show at our wedding. My father passed away about 6 years ago. My mother has been raising me on her own since I was about 4. I would like to find the perfect song for some pictures of me standing next to his grave. One of the options I have thought about is My Wish by Rascal Flatts. But there is a song I remember hearing about 8 years ago. It was about the wedding day and how the bride wanted her dad to be there, at the end of the song she finds a bouquet of flowers on the table that say "love, Dad" . It brought me to tears, I know that would be the perfect song. If anyone can help, that would be wonderful!!
