2012 Disco Inferno! Yesterday Sister Sledge, Chaka Khan, Grace Jones, Gloria Gaynor and the Pointer Sisters all took to the stage at the Etam Fashion Show In Paris. Dressed up for the occasion in glittering outfits, they gave onlookers a trip down memory lane as they performed their Disco hits from the Seventies. The disco-medley was the perfect accompaniment to the 70s-influenced collection of metallic plunge body-suits and dance floor neons. Take a look of their performance below.
