I’m standing in the bathroom on the upper floor – you really don’t have to know what I’m doing –looking wistfully through the chartreuse-coloured cascade that is the weeping willow at the bottom of our garden and across the canal to Victoria Park. It is `just spring when the world is puddle-wonderful’ as American poet E.E. Cummings once put it, and we can no longer enter it. Like pints after work and an evening at the theatre, our beloved park is just a memory. It’s encaged by tall iron gates.

Most English people are familiar with the song Jerusalem which is a kind of unofficial national anthem for England - as opposed to God Save the Queen which is the official anthem for the United Kingdom as a whole. The words were written by the poet and painter William Blake, one of the great English eccentrics, a born and bred Londoner.
