It Was More Fun By Boat
Until 1962 the England cricket team travelled to Australia by boat, stopping in Italy, Egypt, Aden and Ceylon. Reminiscences from a fortnight of fun, relaxation, conflict and peril come from Fred Trueman, Tom Graveney and David Allen.
Blimey, you wouldn't want to fall out with Fred Trueman and then spend two weeks sailing the high seas with him.

Two Men In A Trench - The Defence Of Inchkeith The mile long island of Inchkeith sits in the middle of the Firth of Forth on Scotland's east coast and has had a long and dramatic history. Christian monks lived there in the 7th century, it has been an isolation area for syphilis sufferers, a prison and was armed in the first and second world wars. The team goes looking for hidden secrets.
Mysteries Of The Mind
Have you noticed all the dramatic improvements to public transport in London recently? No? Do you know why driving into London is virtually impossible because of the number of road works and 'remodelling' schemes? Readers, I have a theory. Ken Livingstone wants to make driving into London so intolerable that an inadequate public transport system will seem appealing when the time comes for congestion charging. Ironic though, that only those who can afford it will sail into London when the charge comes in, while the poor old proles will get herded onto a system crying out for investment.
Socialism, eh? Londoners have always complained about transport, but these days the name Livingstone crops up with ever more regularity, and it's not in the context of Ken, our saviour, either.
Do you have any theories about what's going on in Ken Livingstone's mind? Write to Foresight.
