Dance with the green fairy at this absinthe-doused soirée as Euston's Grand Hall is transformed into a Montmartre music hall. There'll be Baudelaire-and-Wilde-inspired antics throughout the night as circus freaks and cabaret acts, live bands and ace DJs like Stranger than Paradise's Sacha Dieu make like a debauched, nineteenth century Parisian salon. DC: Devilishly dashing or femme fatale – think twirling moustaches, showgirls and crisp coat tails.
