I listed a few, then went through the thread. All but two of my list have been mentioned more than once. I found just one mention of Steve Goodman's "Ballad of Penny Evans": "Now it's every month I get a check, from some Army Bureaucrat; and it's every month I tear it up, and I send the damn thing back". The one remaining on my list is "Touch a Name on the Wall", by Joel Mabus; nothing else cuts me to the bone in quite the same way: "God damn the liars and tin plated heroes who trade on the blood of such men. God give us the strengh to stand up and tell them...NEVER AGAIN."

As to "Teddy Bear" and "He Stopped Loving Her Today", to me the saddest thing is that people have bought into that level of manipulative maudlin drivel:
He stopped loving her last week;
What's that smell around his door?
Bring a baggy that won't leak;
He stopped loving her last week.
