Even by the standards of bel canto comedies Donizetti’s Le convenienze ed inconvenienze teatrali is insubstantial fluff. It’s basically a farce about a no hope opera troupe failing miserably to rehearse an opera in the face of prima donnaish Prima Donna, her overprotective husband, a flaky German tenor and the overbearing mother of the Seconda Donna (played by a man, natch). Half of the jokes turn on cast members singing badly and the rest on standard opera clichés. None of them are particularly funny. The music is a bit non descript too. The best bits are when the Prima Donna and the tenor inexplicably decide to sing Rossini and Mozart in the middle of a rehearsal.
