The Andrews Sisters

The Andrews Sisters were one of America’s most iconic and successful close harmony singing groups, whose music became a definitive soundtrack for the swing and boogie-woogie eras. Comprised of three real-life sisters—contralto LaVerne, soprano Maxene, and lead vocalist mezzo-soprano Patty—the trio’s upbeat, syncopated style made them international superstars. They are famously associated with the World War II era, where their performances for Allied armed forces and hit songs like “Boogie Woogie Bugle Boy” provided a vital boost to morale. With a staggering career that included numerous films and an estimated 80 million records sold, The Andrews Sisters remain one of the best-selling female vocal groups in history.
