Ms. Andrews and her sisters, Patty and Maxene, were one of the most successful women's singing groups, with 19 gold records and sales of nearly 100 million copies. The sisters began performing in the early 1930s when the Depression wiped out their father's business. In 1937, the sisters scored their first big hit with 'Bei Mir Bist Du Schoen.' In addition to 'Boogie Woogie Bugle Boy', their best-known songs included 'Don't Sit Under the Apple Tree' and 'Rum and Coca Cola'. The trio officially broke up after the death of Laverne in 1967, and a suitable replacement could not be found.
