While everyone knows of Warren Zevon's "Werewolves of London", another great song is "Roland, the Headless Thompson Gunner", about a revenging dead mercenary who stalks the earth looking for Van Owen, who blew his head off in a war in the Congo.

It is on the same album as Werewolves, named Excitable Boy (also a great song about a mentally ill boy who kills his prom date after he "raped her, killed her, then he took her home" and after "10 long years, they let him out of the home" and then "he dug up her grave and built a cage with her bones").
