Inez Foxx (September 9, 1937 – August 25, 2022) and her elder brother Charlie Foxx (October 23, 1933 – September 18, 1998) were an American rhythm and blues and soul duo from Greensboro, North Carolina. Inez sang lead vocal, while Charlie sang back-up and played guitar. Casey Kasem, and doubtless many others, mistakenly thought that the two were husband and wife.
