I read about these events in the Times newspaper and thought I'd post them here for anyone travelling to London this summer.
June 11-26 at Spitalfields market www.spitalfieldsfestival.org.uk
City of London June 21-July 9, spread over 21 venues and ranges from jazz to Baroque, with music from Portugal and Brazil, plus celebrations of Chopin's 200th birthday (my, he IS getting on a bit!) www.colf.org
Enjoy!
