Here's an eyecatching promotion from the Sun newspaper in London.
The paper is taking over all the seats for one performance at the Royal Opera House, Covent Garden. You can put your name in the hat and if you win, you get a chance to buy cheap tickets for Mozart's Don Giovanni.
The tone of the marketing is not aimed at your hoity-toity aesthetes. As the Sun says: "It's full of sex, violence and great singing and is an experience not to be missed." All the details here.
wish me luck!
