Swing Out Sister are a British "sophisti-pop" group best known worldwide for their 1986 song "Breakout". Other hits include "Surrender", "Twilight World", "Waiting Game" and a remake of "Am I the Same Girl?" Though album sales in the U.S. and Europe have levelled off since the early 1990s, the group continues to attract a loyal fanbase. The group is also very popular in Japan.

Although Swing Out Sister is currently a duo, they began as a trio in the UK. The group were formed by Andy Connell (keyboards) and Martin Jackson (drums), and were later joined by Corinne Drewery (vocals). The name came from a 1945 movie starring Arthur Treacher, called Swing Out, Sister, and they claim they chose the name because it was the only thing the band could agree on, in that they all hated it. Both Connell and Jackson had been playing in other bands prior to forming SOS, while Drewery was actually a fashion designer and model before she became the band's lead vocalist.

Together with their producer, Paul Staveley O'Duffy, they signed with Mercury Records. Prior to their first album, they released the single "Blue Mood" in the UK in November 1985. However, it did not chart.
