I've read several times that Princess Diana and William and Kate find Kensington Palace drab, and compared to the gardens, I think they're right. Frankly, a pressure washing wouldn't hurt.
After spending almost the entire day out of doors, we went to Evensong at Westminster Abbey.
For an hour we set right in the middle and heard the most gorgeous choir and organ music. There was no "message" - just reading of scripture. Prayers were all scripted, but the leader sang some of them.
After that, we went to a show - "The Importance of Being Earnest." It was very enjoyable!
