“In our parties we do everything that happens in a ‘wild bash’. We drink hard liquor, we play loud music and dance like there’s no tomorrow,” says Proneeta Mukherjee, who is manager at a Calcutta beauty salon. There’s nothing unusual about this description of a ‘rave do’ except that Mukherjee is not, in her own words, “a spring chicken with whom society associates such wild parties.” She’s a 60-year-old woman who, along with a group of her friends, most of them her age or older, has rediscovered the art of partying. “Sometimes when we shake a leg, our knees knock together and our bones rattle, but we don’t stop,” quips Mukherjee. “Instead, we try to synchronise the sound of our creaking joints with the beat of remixed versions of retro tunes we had grown up listening to.”
