Bananarama are an English female pop duo who have had success on the pop and dance charts since 1982. Rather than relying on a two part harmony, the duo generally sings in unison, as do their background vocalists. Although there have been line-up changes, the group enjoyed most success as a trio made up of lifelong friends Siobhan Fahey, Keren Woodward and Sara Dallin. In 1988, Bananarama were listed in the Guinness World Records as the all female group with the most chart entries in the world, a record which they still hold.
