Jacquie O'Sullivan (born 7 August 1960)[1] is an English singer and songwriter, best known as a member of the pop group Bananarama from 1988 until 1991, replacing Siobhan Fahey, who left in early 1988.
They re-recorded the vocals for the songs "I Want You Back" and "Nathan Jones" with O'Sullivan to replace versions previously recorded by Fahey.
O'Sullivan's only songwriting credit with Bananarama appeared on the song "Love, Truth and Honesty" from the compilation album Greatest Hits Collection.
O'Sullivan later stated in interviews that her role in Bananarama was that of a paid employee and that she was given no say in the creative, musical or visual direction of the group.
She said that this lack of input, along with the continued emphasis by the music press that she was the "new girl" and constant questions of "How does it feel to replace Siobhan?
When French and Saunders parodied Bananarama in their 1988 Christmas special as "Lananenenoonoo", O'Sullivan was portrayed by Kathy Burke as "Kim".
In 2001, O'Sullivan signed a three-album deal with AlmaFame Records, featuring unreleased songs from throughout her music career.
