The Society of Box Office Managers (SOBOM) is a group of staff from across the London theatres, meeting regularly for socials and events. Every year they are also subjected to the SOBOM Quiz - a fiendishly hard occasion for even the best theatre enthusiasts.

How well can you do? With rounds based on themes of 'Arts and Literature', 'Sport' and 'Science and Nature' (though obviously with a theatrical twist...), only the toughest theatre nuts can get 20 out of 20.
