McNair recorded three more singles for Coral in 1958 -- He's Got the Whole World in His Hands, Indiscreet, and Too Late This Spring, respectively -- followed in 1959 by Goin' Steady With the Moon, Lover's Prayer, and Telephone Conversation, the latter a duet with Billy Williams. She also toured with Nat King Cole, appearing in his stage shows #I'm with You and #The Merry World of Nat King Cole. McNair then signed to the Signature label for three 1960 singles -- He's a King, All About Love, and Kansas City -- followed by a tenure at Roulette that yielded 1961's That's All I Want From You, and the following year's Honeymoonin.' She landed at KC for Cross Over the Bridge, and in 1963 made her film debut opposite Henry Fonda in #Spencer's Mountain -- she also appeared in guest roles on a number of TV series, among them #Dr. Kildare, #I Spy, and #Hogan's Heroes.
After a one-off 1965 effort for Warner Bros., Wanted Me, later that same year McNair signed to Motown, scoring her biggest hit with her label debut You're Gonna Love My Baby. Everything Is Good About You and My World Is Empty Without You followed in 1966, as did sessions for Baby a Go-Go, arguably her strongest disc to date -- remarkably, Motown head Berry Gordy rejected the single, however, and it went unreleased for decades, until bootleg copies earned rave reviews from the DJs and dancers populating Britain's Northern Soul club circuit. (Motown finally gave Baby a Go-Go a legitimate release on the 2002 compilation A Cellarful of Motown!) McNair's Motown run ended with a pair of 1968 singles, Where Would I Be Without You and You Could Never Love Him; from that point forward she directed more and more of her energies into her acting career, returning to the big screen in the crime drama #If He Hollers, Let Him Go! followed in 1969 co-starring with a role in the Elvis Presley vehicle #Change of Habit.
The syndicated variety series #The Barbara McNair Show also premiered in 1969, running for three seasons; in 1970, McNair scored her biggest screen role to date appearing opposite Sidney Poitier in #They Call Me Mister Tibbs!, the sequel to the Oscar-winning #In the Heat of the Night. She also co-starred in the follow-up, 1971's #The Investigation, but was largely out of the spotlight for the remainder of the decade, appearing on stage, in nightclubs and the occasional TV guest shot while taking time-out in 1976 to record one last single for TEC, Because of You. In 1984, McNair accepted a recurring if short-lived role on the daytime soap opera #General Hospital, and in 1996 she returned to feature films after a quarter century absence in the little-seen #Neon Signs. In addition to her own headlining nightclub dates, she also starred in +Sophisticated Ladies, a stage tribute to the music of Duke Ellington. ~ Jason Ankeny, Rovi
