Becker and Fagen favored a distinctly soul-influenced style of backing vocals, which after the first few albums were almost always performed by a female chorus (although Michael McDonald features prominently on several tracks, including the 1975 song "Black Friday" and the 1977 song "Peg"). Venetta Fields, Sherlie Matthews and Clydie King were the preferred trio for backing vocals on the group's late 1970s albums. Other backing vocalists include Timothy B. Schmit, Tawatha Agee, Brenda White-King, Carolyn Leonhart, Janice Pendarvis, Catherine Russell, Cynthia Calhoun, Victoria Cave, Cindy Mizelle, and Jeff Young. The band also featured singers like Patti Austin and Valerie Simpson on later projects such as "Gaucho".
