Sad songs for graduation Elementary school

Hey guys,

This is completely off-topic

I am making a song / slideshow for children leaving primary school (11-12 years old), wich will have pictures of them as young kid and now. I am looking for songs to put under it.

I already have slipping through my fingers from Abba, and See you again from charlie putz, but i am looking for more. Do you know any sad songs about growing up? Especcially from parent / teacher to child?

Let me know!

This is more of a wedding song, but I suppose it can work for your project as well.
