Casual operagoers of London! Here's a useful tip for you. If you ever find yourself purchasing a ticket for the English National Opera, be sure to give them your mobile number and ask them to pester you with marketing offers. Ironically, I did just that in 2010 for a production that I wasn't able to attend on the day - the Punchdrunk collaboration The Duchess Of Malfi, which by all accounts was a bit of a dud anyway.
But since then, whenever ENO has had a few spare seats going for a particular production, they've sent me a text on the day offering them at a massively reduced rate. Which is how I started one day last week with no plans for the evening, and ended it sitting in an Upper Circle seat at the Coliseum that cost me £20 instead of the usual £59, watching THE MOST CONTROVERSIAL OPERA IN THE WORLD.
