The American-born actor Beth Porter, who has died aged 81, had a varied career that took off in her homeland with experimental theatre before she moved to Britain and reached a wider audience in two groundbreaking television series.
In Rock Follies of 77, a sequel to 1976’s Rock Follies, she had a strong supporting role as Kitty Schreiber, the tough, wheeler-dealing American managing the gutsy Little Ladies singing trio played by Julie Covington, Charlotte Cornwell and Rula Lenska.
