Neil Young: "Powderfinger"

look out, mama
there's a white boat
coming up the river
with a big red beacon
and a flag
and a man on the rail
i think you'd better call John
beause it don't
look like they're here
to deliver the mail
and it's less than a mile away
i hope they didn't come to stay
it's got numbers on the side
and a gun
and it's making big waves
