Just thought, that since it dates from 1984 or thereabouts, not everyone might have heard of "Rocket launcher", from Bruce Cockburn's "Lovers in a Dangerous Time" LP (as it then was). So here goes:-

START
Here comes the helicopter -- second time today
Everybody scatters and hopes it goes away
How many kids they've murdered only God can say
If I had a rocket launcher...I'd make somebody pay

I don't believe in guarded borders and I don't believe in hate
I don't believe in generals or their stinking torture states
And when I talk with the survivors of things too sickening to relate
If I had a rocket launcher...I would retaliate

On the Rio Lacantun, one hundred thousand wait
To fall down from starvation -- or some less humane fate
Cry for guatemala, with a corpse in every gate
If I had a rocket launcher...I would not hesitate

I want to raise every voice -- at least I've got to try
Every time I think about it water rises to my eyes.
Situation desperate, echoes of the victims cry
If I had a rocket launcher...Some son of a bitch would die
END

Strong stuff, no? Maybe too strong for some. Anyway, thought it followed the theme of this thread quite well.
