The Andrews Sisters were an American close harmony singing group of the swing and boogie-woogie eras. The group consisted of three sisters: contralto LaVerne Sophia (July 6, 1911 – May 8, 1967), soprano Maxene Anglyn (January 3, 1916 – October 21, 1995), and mezzo-soprano Patricia Marie "Patty" (February 16, 1918 – January 30, 2013).[1] It is claimed that the sisters have sold more than 90 million records.[2] Their 1941 hit "Boogie Woogie Bugle Boy" can be considered an early example of rhythm and blues[3][4] or jump blues.
