I first heard this song over 40 years ago and learnt it. I decided recently to relearn it only to find I have lost the words. I can remember most of it but cannot recall the final verse.

It starts :

Everybodys crowding down, heading for the underground
Friday times crush is pushing home
poker faced and zombie eyed, eyes upon the routing ride
and a fight to gain a seat for them alone
on the platform someone yawned, there was talk of trimming lawns
everyone ignored the ringing bell
but the stationmaster knew for a message had come through
and he stopped to tap the dust of his lapel

And it was chalked on a blackboard sign
in letters plain as day body on the line
sorry for delay
