Another nest - and more music

Went up to London today to see and hear Errollyn Wallen's opera Anon at the Tete-a-Tete festival.

Afterwards I was hoping to catch the final hour of Marina Abramovic at the Serpentine Gallery, but it closed before I got to the top of the queue. So I had coffee and a bun, and had time to loiter by the coot's nest on the Serpentine on my walk back to Paddington.
