The Goodmans broke new ground in gospel music during the 1960s and 1970s by implementing a live band and creating their own unique sound. It was during these years that they developed their now classic "grab a note and hang on" endings. Sam's humorous emcee work, Howard's showmanship at the piano, Rusty's songwriting, and Vestal's hairdos, white handkerchiefs, and powerful singing voice all rose to a new prominence. Tenor Johnny Cook joined the group for a while in 1974 and Rusty's daughter Tanya was added in 1976.
