Johnson was a member of The Johnson Family, which sang gospel and country music for two decades. President Franklin D. Roosevelt was a fan; the group was invited to sing at his memorial service. Johnson went solo in the late-1950s, and was a regular on Don McNeill's "Breakfast Club" and Jack Paar's TV show. After making a dozen records, she left show business to raise a family and earn a degree in drama at Dartmouth. She has since returned to her singing career, with a cabaret act at The Oak Room. Her new album is called "A Family Affair."
