In the car on the way to my Grandmother's burial after her funeral, we heard this song. My Dad just broke down in tears. The song tugs at your heartstrings anyway but to add the funeral element it just breaks my heart. To this day, I still can't listen to the whole song.
As I've gotten older, this song totally illustrates the relationship between me and my parents (as I'm sure is the same for LOTS of parent/child relationships).
