The Trafalgar Square switch-on

Here we are in Old London Town, and already we've tired ourselves out silly after lunch at St Martin's, Oxford Street to see the lights, the Trafalgar Square tree lights switch-on (where were the carol singers?) and back to L'hotel via Waterstones and Fortnum's. Phew.
A nice cuppa follows...
Tate Britain and The Preraph's tomorrow, then Kensington Palace and The Orangery on Saturday.
