Christmas spectacles, slapstick, and beanstalks have been drawing crowds to Covent Garden since 1737. John Rich, the first manager of what is now the Royal Opera House, was a fine dancer, mime, and special effects man and he (and his successors) developed all the well known features of the  London Christmas season. Even now principal boys, fairies, and Harlequin are alive and well on  the ROH stage. This lecture pulls together the whole performing tradition and brings it up to date with the latest Christmas offerings at the Royal Opera House.
