OLIVIA NEWTON-JOHN AT THE BBC

The four-time Grammy Award winner and beloved star of Grease lost her long battle with cancer in August at the age of 73. In tribute, this trip down memory lane draws on archive performances and interviews to take an affectionate look back at the life and career of the singer (left) who was born in Cambridge but moved to Australia aged five. It’s followed by the chance to see her star opposite Gene Kelly in the dazzling musical fantasy Xanadu (11.15pm) and Only Olivia (12.50am), a 1978 TV special in which the singer, dressed in a long flowing white dress, performs a selection of ballads and feeds horses in the countryside. It’s all very 1970s. Saturday, 10.15pm, BBC2
