The Yandall Sisters were a popular New Zealand-born Samoan all-female singing group of the 1970s, who made a major contribution to music in New Zealand. The members of the group were Caroline, Mary and Adele Yandall, and later younger sister Pauline Yandall. In 1974, their hit song "Sweet Inspiration" stayed on the NZ Top 20 singles chart for eight weeks, and has become a classic favourite in New Zealand and the Pacific Islands. The track was a cover of the song by an American group of the same name.
