The English National Opera will produce La Boheme this summer in the middle of Trafalgar Square. The production is expected to draw an audience of 8,000. Tens of thousands more are likely to spill over on to surrounding pavements, the steps of the National Gallery and any space near enough to catch the amplified sound. La Bohème is the first opera to be put on in the square, an event that will trump the impresario Raymond Gubbay’s recent success in staging the same work in the Albert Hall.”
