I'm passing through London later this week. Main errand is to push ahead the clothing production, but shops are closed evenings. And like an idiot, I waited until Henry IV was sold out before making enquiries. All the agencies I've found on-line or as a referral from the box office are saying No. Does anyone know a good source for sold-out tickets (in London or on-line), or a good way to scrounge a seat before show time? And if you want to make my week, does anyone have a single ticket for Thursday's show?
