Martin's rough-hewn singing style, combined with the enthusiastic physicality of the Holiness church, nearly kept her from working with Dorsey, who looked down on the shouting style of many Holiness singers and was reluctant to hire a singer who could not read music.
Martin nonetheless persuaded Dorsey, after three auditions, to hire her as part of a trio he had formed to introduce his songs to churches.
They were responsible for publishing a number of gospel standards, including Just a Closer Walk With Thee (1940).
She remained an active force in the NCGCC even after she went out on her own and was a vocal supporter of Martin Luther King Jr. and of health programs in Nigeria.
She remained a vigorous proponent of gospel music and defender of her role in bringing it to the churches, as her appearance in the 1982 movie Say Amen, Somebody illustrates vividly.
