About the shows, it seems it's easy to get a good seat on short notice if one is looking only for one seat.
On Friday nights, the British Museum is open late, so on my way to the Prince Edward Theatre to see the Jersey Boys, I dropped in only for a monent to check out the opening times for the next few days. Then off to the theatre.
Both of the shows I saw were absolutely wonderful; the acting, the sets, the singing & music, the theatres themselves; all brillant.
This is looking at the Parliment Building from Parliment Square. The detail of this place is amazing.
When travelling to London, pick out the sights you want to see and check their opening times. They don't always conform to what you might think is appropriate.
I finished up my walk this day at Buckingham Palace. That day, the guard had changed at about 11am. I got there at 4pm, but the views were fantastic none the less.
