...by the prospect of seeing the legendary Don Johnson playing the lead role of Nathan Detroit in the Piccadilly Theatre's production of Guys & Dolls, I ask you?
The Underground is plastered with advertising posters for it. What, they couldn't afford The Hoff?
But at least that goes to show that London is quite a bit cleaner than it used to be. Back in the day, faces such as Mr Johnson's would have been liberally adorned with knots of used chewing gum, which served the dual purpose of spontaneous consumer feedback on Underground poster advertising campaigns, and solved the problem of the lack of rubbish bins for commuters.
