Famed British 20th century orchestra conductor Sir Thomas Beecham was attending a performance of Puccini’s opera ‘Aida’ in London, a lavish affair with majestic sets and a large complement of singers, including at one point, elephants being brought on to the stage.

Answer: ‘Terrible stage manners. But what a critic!’
