Watch Bombuj. Henry VIII, Queen Victoria and Wolfgang Amadeus Mozart are our hosts for a special live concert as part of the BBC Proms season at London’s Royal Albert Hall, introducing us to the world of opera. Mozart is sure that the Horrible Histories audience will love opera, with all its grisly and gruesome stories. But Queen Victoria is not so sure, thinking opera is totally unsuitable for children. In fact, she thinks the audience need to leave at once! Can Mozart change her mind?
