Your grandfather sounded like a cool guy, Luca. You're lucky he was around for such a large part of your life, and that you had the time and opportunity to get to know him.
Because my dad was a geophysicist - involved first in oil exploration and later in earthquake seismology - we moved a *lot* while I was growing up, and became completely disconnected from relatives. I never really got to know any of my grandparents, or even aunts, uncles and cousins.
Not until this very moment have I given much thought to how that disconnectedness influenced the life of my immediate family, but I realize that it was considerable.
I think it sounded great how everyone laughed and sang along with the railroad song during the service. I imagine your grandfather was well aware that his request for that song would have such an effect. Cool.
