I’m back in London again and here’s one of its best-known landmarks. Actually this hasn’t been called the ‘Post Office Tower’ for a very long time — these days it’s the ‘BT Tower’. But for my generation this always was the Post Office Tower and always will be. Tallest building in the UK from when it was built in 1964 until 1980. There’s still something cute about it; it reminds me of a big light bulb, for some reason.
