New York, 1977. In a former opera house on West 54th Street, Studio 54 became the most famous nightclub in the world, the place where disco was at its best and the nights never seemed to end. They say that on Halloween, spirits come back. This year, the spirit of Studio 54 is coming to London. Halloween was never really about being scared. It was about dressing up, letting go and becoming someone else for a night. The theme is disco. Dress like it's 1977.
