From the wiki: “‘Neither One of Us’ was written and first recorded by Jim Weatherly, found on his 1972 album Weatherly. Weatherly was an All-American quarterback at the University of Mississippi before choosing songwriting over a football career. Bob Luman charted first with ‘Neither One of Us’, making it into the Top 10 Country in 1973.
“Weatherly’s songwriting was something of a ‘goose with golden eggs’ for Gladys Knight & The Pips. In addition to recording ‘Neither One of Us’, the group also ‘hit’ with two other Weatherly-penned songs: ‘(You’re the) Best Thing That Ever Happened‘ and ‘Midnight Train to Georgia‘ (originally titled ‘Midnight Train to Houston’).”
