I always sang along on the “live by the river” part, but I never actually knew what the rest said until I saw it written out.

The ice age is coming, the sun is 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

Joe Strummer & Mick Jones
The Clash, “London Calling,” London Calling, (1979)
