The Stevens Sisters are actually two sets of sisters, with 100 years of barbershop experience between them. They have sung together for about 6 years, although the tenor, lead and baritone have sung together for longer. Tenor Shirley Stevens and lead Suzy Martin are sisters and baritone Lyndy Stevens and bass Angie Brunton are sisters. Shirley and Lyndy are not related. They like to sing 30's 40's and 50's music.
