If you ever get the chance to see Poppy in one of her plays just do it, you will be in for a treat.
Her latest effort was an impro bit, in the genre of Clive Anderson's 'Whose line is it any way', where she and three other actors, got up and mixed a bit of a script with questions from the audience.
i don't think it would be giving too much of the plot away to say that it's about a group of actors discussing the play that they've just performed, in the green room of the theatre. The audience don't get to see the play, but just to ask questions to the cast after the performance.
Apparently the next performance is in Bristol, and if you do happen to be in the area, do give it a go.
The other good thing, was that the tickets were only £6 per hit, which in London is a real snip for live theatre.
