this time that her act and image altered. Against her mother's wishes, Driver and her sister modernised her performance and Driver became a ballad singer. Shortly after, during a six-month run in a revue called Twice in a Blue Moon, Driver and her sister parted company with their mother following a cardiac asthma attack which restricted her mobility. Driver continued in variety, opening in the Coventry Hippodrome and sharing the bill with the Andrews family - father Ted, mother Barbara and Julie. She made regular trips to Bristol to sing on a radio show called Ack Ack Beer Beer and made her final film in 1941 Facing the Music. In the 1940s, she became a singer in the big bands. During the Second World War, Driver travelled with ENSA (Entertainments National Service Association), entertaining the troops. She also appeared for seven years on the radio show Henry Hall's Guest Night and on her own show, A Date with Betty, which was broadcast live from the People's Palace in London's East End on 14 July 1949. The show's format was based around Driver singing, doing sketches and introducing guests. All her words were scripted by Bob Monkhouse, then barely out of his teens. She recorded many popular tunes in the 1940s and became an established singer during this time. Aged 14, she made her first record "Jubilee Baby", had another major success with "The Sailor with the Navy Blue Eyes", and made several more hit records. Driver travelled to Australia, where she performed her own show, and her career also took her to Cyprus, Malta and the Middle East. On her return to England she appeared in the Ealing Comedies, on stage in The Lovebirds, Pillar to Post and What A Racket, and on television with James Bolam in Love on the Dole. In 1964, she auditioned for the role of Hilda Ogden in the television series Coronation Street (the role went instead to Jean Alexander, for the casting directors wanted an actress of slighter build). Driver was cast later, alongside Arthur Lowe, in the series Pardon the Expression, a spin-off of Coronation Street. She has described Lowe as "such a difficult man to work with"; after a much-publicised injury (she damaged her back after the script called for her to throw Lowe), she retired and began running a pub, the Cock Hotel in Whaley Bridge, Derbyshire, with her sister Freda.
