Mark Shenton: “I always apply the test I also use on theatre tickets to assess how useful they are: would I pay ready money to have one? And the answer is hardly ever. Yet theatre programmes have become a habit for many. They are part of the theatregoing ‘experience’ and a happy aide-memoire of the show. But, I often find the information I need just as easily online. A front of house notice will typically list the cast at a particular performance – especially important with long-running shows where substitutions often appear. So I simply take a photograph of it.”
