She was one of the few members of London society who remained close friends with Margaret, Duchess of Argyll after the "headless man" scandal which, combined with the Profumo affair involving Christine Keeler, threatened to topple the Government of the day.
In the 1970s she began running the Embassy Club in Mayfair, which was London's first modern New York City–style nightclub and which attracted many celebrities, including Marvin Gaye, who became a frequent guest at Lady Edith's estate at Sherston, Wiltshire.
The Embassy had been revived spectacularly by Jeremy Norman, opening in 1978 at almost the same time as the dance film Saturday Night Fever premiered.
The Club opened with a star-studded fashion show by Ossie Clark, where guests included Lady Diana Cooper and Margaret Campbell, Duchess of Argyll.
During the period of Norman's ownership, the Embassy played host to nearly all the prominent names in the entertainment, fashion and young society worlds – a melting pot and crossroads of many cultures.
