Peggy Lee has made a great contribution to popular music, not only as a singer, but also as a lyricist and composer. In this four-part series looking at her life and work, Mel Hill begins in the twenties in North Dakota, where she was brought up by a kindly but weak father and an abusive stepmother. While still at school, she sang on local radio and with semi-professional bands, before graduating to nightclubs and then to the Ambassador Hotel in Chicago. Repeated from Monday 3.45pm
