6/6. Desmond Carrington profiles six historically significant entertainers from the worlds of cabaret, nightclub, revue and theatre. He concludes his survey with a tribute to the inimitable character actress, comedian and singer Joyce Grenfell , who died in 1979, aged 69. She remains lovingly remembered for her galumphing roles in the St Trinian's films and The Happiest Days of Your Life (1950), TV's Face the Music, and countless songs and monologues written with Richard Addinsell.
