Freddie De Tommaso made waves last year when a halftime jump-in made him the first British tenor to sing Cavaradossi at the Royal Opera since Charles Craig in 1963. Now De Tommaso is back at Covent Garden to sing the role and this time the cast includes Natalya Romaniw, the first British soprano to sing Tosca at Covent Garden since Gwyneth Jones owned the part back in the 1970s. Indeed, a pair of Brits have not sung opposite each other in Puccini’s opera here since 1954.
