Art? What is it and what’s it for? These eternal questions kept coming up on our very artsy visit to London last week, where we took in:   Hajj: journey to the heart of Islam at the British Museum; Dickens & London at the Museum of London; the play “The Pitmen Painters” at the Duchess Theatre on Drury Lane, and even a visit to ancient Stonehenge.
