When I was a teenager one of my friends died. He had several brothers who stood as his pallbearers, and they carried the casket from the funeral home out to the gravesite.
The song they played was "He ain't heavy, he's my brother" and while up until that point I had always found the song to be a bit hokey, after that, and to this day, I can't hear it without getting a lump in my throat and tears in my eyes.
It was a long and very powerful walk ...
FWIW.
