Shakespears Sister is a British-based pop-rock act formed by Irish-born singer–songwriter Siobhan Fahey in 1988. Initially, Shakespears Sister was essentially Fahey by herself but, from 1989, the act became a duo of Fahey and the American musician Marcella Detroit. Together they released two Top 10 albums and a string of Top 40 hits, including the 1992 hit "Stay" which peaked at #1 in the UK for 8 consecutive weeks. Detroit left the band in 1993, leaving Fahey as the sole member again until she ended the project in 1996. After working under her own name for some years, Fahey revived the Shakespears Sister name in 2009.
