The performance was amazing, my seat (B2) was totally uninhibited, Roberto Bolle as ONEGIN was perfection BUT during the third act, during the big lifts, members of the audience kept taking photos with flash! What is wrong with people? Can t they just watch it and enjoy it for what it is? No announcement was made prior to the performance about mobiles off etc., but surely that s a given!
