We had a fantastic day today, going back to the Beatles store on Baker Street so the little production assistants, who are huge Beatles nuts, could get themselves proper souvenirs. We then went to the Natural History museum so the younger two and their dad could go ooh and aah at dinosaurs. Eldest and I, not the biggest dinofans around, went for tea and croissant in Kensington then to Picadilly Circus then Buckingham Palace then reunited with the rest of the family and our two musicians from the Magna Carta shoot last year. We all went for lunch on a boat on the Thames, and we finished the day with a very special treat: a visit to the Tower of London (for which we thank Isabel very much). We are flying home in the morning. And everyone is sad to leave. Maybe we'll be able to come back some day.
