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.
In 1977, the Yandall Sisters were named New Zealand Group of the Year. Popular entertainers in their own right, they have provided backing vocals for hundreds of musicians and entertainers, in New Zealand and Australia. These include notable showbands and Maori artists including the late Prince Tui Teka, the late Sir Howard Morrison, the late Bunny Walters and John Rowles.
Mary Yandall recorded an album with Rodger Fox in 1987. She died aged 62 on 30 January 2012 at Auckland Hospital after a short illness.
