The Three Degrees are a female Philadelphia soul and disco vocal musical group, formed in 1963 in Philadelphia, Pennsylvania. Although it has always had a three-girl lineup, the group has undergone numerous personnel changes, and a total of twelve women have represented the trio so far. The original members were Fayette Pinkney, Shirley Porter and Linda Turner. The trio, tagged by the media as "Prince Charles' favourites", were the first girl group to top the UK Singles Chart since The Supremes in 1964.
