Harry Chapin, "Sniper"

Let's try an experiment: The next time you have a party, play this song--then see how many people stick around. It's a well-written ballad with a great performance, but in general, a 9+ minute ballad on the 1966 University of Texas massacre is kind of a downer.

I'll give extra credit points to anyone who can do a mash-up with this tune.
