Not re the workers beer but the terrible knob as per Suzanne, wow, that brought back some memories but I can't remember all of it but it goes

1. I'm the man, the terrible man, in charge of the terrible knob.
The most pleasing thing about it is it's almost a permanent job.
When the atom war is over and the world is split in three,
A consolation I've got, or maybe it's not, there'll be nobody left but me.

2. If me wife denies me conjocular rights or me breakfast milk is sour,
From eight to nine in the morning, lads, you're in for a terrible hour;
For the button being so close to me, it really is a joke;
A butt of me arse as I go past, and we'll all go up in smoke.

Try as I might I can't remember anything else! Does anyone else know the rest ...just to put me mind at rest?
