The Andrews Sisters were a highly successful close harmony singing group of the swing and boogie-woogie eras. The group consisted of three sisters: contralto LaVerne Sophia, soprano Maxene Angelyn , and mezzo-soprano Patricia Marie "Patty" Andrews. Throughout their long career, the sisters sold well over 75 million records (the last official count released by MCA Records in the mid-1970s). Their 1941 hit "Boogie Woogie Bugle Boy" can be considered an early example of rhythm and blues or jump blues.
