From The Box Office has posted a humorous 'who's who' guide to Les Mis on its blog which I think fans will enjoy.
I laughed out loud at the tongue-in-cheek character descriptions, especially Fantine - "a single mum with a fizzy drink-sounding name who just can't find good childcare," and Eponine "whose flasher coat turns out to be neither water nor bulletproof and totally unsuitable for a revolution."
