Quartet for war

"A lunchtime recital by the Jerusalem Quartet, broadcast live on Radio 3, was disrupted by anti-Israeli protestors and taken off air. During the first half of the performance at London’s Wigmore Hall yesterday, a group of demonstrators in the audience stood up and began to shout and chant. They were removed from the venue, and the concert continued; the Radio 3 broadcast was replaced by a performance by the Salomon Quartet." (thanks John)
