i have to go with "i feel like i'm fixin'to die rag" great song
it has an unforgetable chorus:
and it's one, two, three,
what are we fightin' for?
don't ask me, i don't give a damn,
next stop is vietnam;
and it's five, six, seven,
open up the pearly gates,
well, there ain't no time to wonder why,
whoopee! we're all gonna die.
