That sucks man.
I'm a big Eels fan, but I don't dare to put this song anymore when a friend of mine is around, because his mother died of cancer and it pretty much reduces him to a depressed mess.
So I know you're going pretty soon,
Radiation sore throat got your tongue.
Magic markers tattoo you, and show it where to aim.
And strangers break their promises, you won't feel any...
You won't feel any pain.
With my family, our longer car-trips have a tendency devolve into hour long renditions of "We All Stand Together", but other than that I don't think there's anything else that really defines my family, music wise, though.
