The DeCastro Sisters was a female trio singing group: originally they consisted of Peggy DeCastro (1921–2004), Cherie DeCastro (1922–2010) and Babette DeCastro (1925–1992). When Babette retired in 1958, a cousin, Olgita DeCastro Marino (1931–2000) replaced her and when Peggy later left the group to go solo, Babette re-joined Cherie and Olgita. Peggy eventually returned and Babette once more retired.
They began as a Latin-flavored trio, strongly inspired by The Andrews Sisters and were protegees of Carmen Miranda. They eventually became more Americanized in their performances and added a lot of comedy, but continued to have a unique and exotic identity of their own.
The biggest hit single for the group was "Teach Me Tonight", in 1954. The song hit #2 in the United States, and the follow-up, "Boom Boom Boomerang", hit #17. The group is referenced in an episode of The Sopranos, "Do Not Resuscitate", as one of the only music groups that matriarch Livia actually likes, along with Mario Lanza.
The three original DeCastro Sisters—Peggy, Cherie and Babette—were raised in Havana in a family mansion that was seized by Fidel Castro during the Cuban revolution and is now used as the Chinese Embassy. Their mother, Babette Buchanan, was a Chicago-born Ziegfeld Follies showgirl who married the wealthy Cuban aristocrat Juan Fernandez de Castro, owner of a large sugar plantation in the Dominican Republic, where first daughter Peggy was born. De Castro later developed radio and television in Cuba with David Sarnoff, who was often a guest at their home and was also in charge of a planned project under the Batista regime to build a canal through Cuba, which never materialized.
De Castro purchased a co-op at the famed Dakota apartments in Manhattan, where Cherie Dawn DeCastro was born on September 1, 1922. Youngest daughter Babette was born back in Havana. The De Castro Sisters, always strongly chaperoned, began their singing careers as young girls and patterned themselves as a Cuban version of the Andrews Sisters. They emigrated to Miami in 1942, where they were seen by an agent from General Artists Corporation (now ICM) and booked into the Copacabana in New York with the Will Mastin Trio featuring Sammy Davis Jr.
