A crowd protest appears to have been closely averted at the Womad World Music Festival. When Ska Cubano, a popular Cuban band, left the stage after a storming evening session, the audience booed and hissed until they returned for an encore, despite being informed that the evening had come to an end by the long-standing Radio 3 presenter Lucy Duran. She tells me she can't remember a more exuberant audience in the history of the Radio 3 stage at the festival: "It was 11.55pm when the band left the stage. The crowd had been so packed that there wasn't a space left. We had to close down the sound by midnight. We had to be silent by then – I had been told by the stage manager that there was to be no encore. She was adamant. I went on stage to tell the audience. I got on the stage and they hollered and booed until finally the stage manager got on the phone and got agreement for an encore. All the while, the crowd was heckling. I've never seen it like that before. When we finally got the thumbs up, I went out and told them 'You've won!'"
