Starting in the ’50s, the McGuire Sisters were one of America’s most popular vocal groups, their three-part harmonies a balm to audiences rattled by rock ’n’ roll.
Phyllis McGuire, the lead singer and last surviving member of the McGuire Sisters, who bewitched teenage America in the 1950s with chart-topping renditions of “Sincerely” and “Sugartime” in a sweet, innocent harmony that went with car fins, charm bracelets and duck-tail haircuts, died on Tuesday at her home in Las Vegas. She was 89. The Palm Eastern Mortuary in Las Vegas confirmed the death but did not specify a cause. Ms. McGuire, with her older sisters Christine and Dorothy, shot to success overnight after winning the televised “Arthur Godfrey Talent Scouts” contest in 1952. Over the next 15 years, they were one of the nation’s most popular vocal groups, singing on the television variety shows of Ed Sullivan, Milton Berle, Andy Williams and Red Skelton, on nightclub circuits across the country and on records that sold millions. The sisters epitomized a 1950s sensibility that held up a standard of unreal perfection, wearing identical coifs, dresses and smiles, moving with synchronized precision and blending voices in wholesome songs for simpler times. Their music, like that of Perry Como, Patti Page and other stars who appealed to white, middle-class audiences, contrasted starkly with the rock ’n’ roll craze that was taking the world by storm in the mid-to-late ’50s. In 1965, as the trio’s popularity began to fade, Phyllis McGuire’s image as the honey-blonde girl next door was shattered by published reports linking her romantically with Sam Giancana, a Chicago mobster with reputed ties to the Kennedy administration and a Central Intelligence Agency plot to enlist the Mafia in what proved to be unsuccessful attempts to assassinate the Cuban dictator Fidel Castro. Mr. Giancana and Ms. McGuire, who had been followed by federal agents for several years, appeared before a grand jury in Chicago. He refused to answer questions and was jailed for contempt. She testified that she had met him in Las Vegas in 1961, traveled with him to Europe, the Caribbean and elsewhere and accepted his gifts in a continuing relationship.
