It takes a particularly wilful wit to alight on Berlioz’s Béatrice et Bénédict as the perfect operatic nod to a Shakespeare anniversary. To walk past Verdi’s Otello, Falstaff and Macbeth, to pass over Purcell’s Fairy Queen, Gounod’s Roméo et Juliette and Bellini’s I Capuleti e i Montecchi and instead opt for this curiously and idiomatically French piece of musical flummery, in which Shakespeare’s Much Ado About Nothing finds itself stripped of any sour notes and whipped up into a sugary dramatic froth, is bold indeed.
