Sorry about the quality of the picture but the most relevant bits are the opening and closing lines:
"Jack and the Prime Minister were in darkness standing on a stationary Northern Line train. The Prime Minister hated the dark.......
"Now he was hanging on a handle that was suspended from the ceiling of the train, sweat running between the push me up and squeeze me together cups of his wife's brassiere. A madman began to shout about Sir Cliff Richard - accusing him of forcing Hank Marvin to become a Jehovah's Witness"
As the poster implored us to "read more" I'm certainly tempted to.
