Nuit blanche I: Dancing at the Centquatre

On a more cheerful note from a slightly earlier era, long live the return of the bal populaire -- dancing 1940s style complete with braces, net veils and accordions! The place may have once been a morgue but it seems no less jolly for the experience, and to top it off there's a late-night bookshop selling postcards of old photos captioned with truly appalling puns -- who but the French could pour half their science budget into la fission de la tomme?
