Have you ever heard the Monkees' song Last Train to Clarksville? It seems like a nice song but it's actually about a last visit at the train station before some guy gets shipped off to Vietnam ... "And I don't know if I'm ever coming home ..." Did you ever hear the M*A*S*H theme song? It is actually a song entitled Suicide is Painless. Did you ever hear the song about the six-pence, pocket full of rye, four and twenty blackbirds baked in a pie!?
