Frankie Armstrong is an English singer and voice teacher. She has worked as a singer in the folk scene and the women's movement and as a trainer in social and youth work. Her repertoire ranges from traditional ballads to music-hall and contemporary songs, often focusing on the lives of women.

The Critics Group, also known as The London Critics Group, was a group of people who met to explore 'how best to apply the techniques of folk-music and drama to the folk revival' under the direction of Ewan MacColl and Peggy Seeger, with some participation from Bert Lloyd and Charles Parker. Running for eight years from the mid-1960s to the early 1970s, it was not a conventional musical group or band as it had no permanent line-up. Members would perform with each other on an ad-hoc basis as situations demanded.
