Lady Linda Wong Davies, Founder and Chairman of the KT Wong Foundation, entertained a number of friends to a screening of a film on the making of Einstein on the Beach, the abstract 1985 opera created by Philip Glass and Robert Wilson.
The two producers took the stage after the screening and answered questions from the audience.
BBP sat next to Bianca Jagger who was one of few people to have seen the opera in its entirety.
The screening was followed by a private dinner, hosted by Lady Davies, and attended by Ms Jagger, Sydney Picasso, Bruno Wong, Alan Yentob, Robert Wilson, Dr Klaus and Mrs Zumwinkel, Philip Glass, and a number of prominent artists and collectors.
Einstein on the Beach will be performed to a sold out Barbican on the 4th May.
