At the Mulberry party on Soho House's roof, Florence and the Machine played an acoustic set (her voice, a guitar and a harp) for about 200 lucky onlookers, most of whom (all but about 50 of us) were idiot fashion fools talking throughout the set.
They played six songs, ending with Dog Days, and calling designer Emma Hill on stage twice to thank her.
Kelly Osborne and Alexa Chung celebullied their way to the front of the intimate show.
All in all, great show, potentially ruined by loud celebutards, and their wispy accouterments.
