Whatever happened to the Persian Gulf?

It appears that the thought-provoking non-fiction smasharoo Whatever Happened to Tanganyika? is read in all the best radio production offices, and when they think geographical name-changes, they think Campbell. It seems I am going to be on the BBC World Service discussion programme World Have Your Say between about 6 and7pm tonight. Which is to say in less than an hour. Sorry you missed it!
