Watch What You Sing

Some songs just seem suspicious:

British anti-terrorism detectives escorted a man from a plane after a taxi driver had earlier become suspicious when he started singing along to a track by punk band The Clash, police said Wednesday.

...The taxi driver had become worried on the way to the airport because Mann had been singing along to The Clash's 1979 anthem "London Calling," which features the lyrics "Now war is declared -- and battle come down" while other lines warn of a "meltdown expected."

So, just what are these words?

london calling to the far away towns
now war is declared and battle come down
london calling to the under world
Come out of the cupboard, you boys and girls
London calling, now don't look at us
Phoney Beatlemania has bitten the dust
London calling, see we ain't got no swing
'Cept for the ring of that truncheon thing

[Chorus]
The ice age is coming, the sun zooming in
Meltdown expected, the wheat is growing thin
Engines stop running, but I have no fear
'Cause London is drowning-and I live by the river

London calling to the imitation zone
Forget it, brother, you can go it alone
London calling to the zombies of death
Quit holding out-and draw another breath
London calling-and I don't wanna shout
But while we were talking-I saw you nodding out
London calling, see we ain't got no highs
Except for that one with the yellowy eyes

[Chorus x2]

the ice age is coming, the sun is zooming in
engins are stoppin the wheat is growing thin
nuclear error but i have no fear
london is drowing and i live by the river

Now get this
London calling, yes, I was there, too
An' you know what they said? Well, some of it was true!
London calling at the top of the dial
After all this, won't you give me a smile?

I never felt so much a' like
