In 1945, the DeCastro family moved to the United States from Cuba. The sisters became protegees of Carmen Miranda, and formed a singing trio in Miami, Florida. They had a style something like the then-popular Andrews Sisters, but with a Latin flavor.
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.
Peggy, the eldest of the group, died 6 March 2004 of lung cancer at age 82. Olgita died on 14 February 2000 at age 65.
The group is referenced in the episode of "The "Sopranos" entitled "Do Not Resuscitate." A favorite group of Tony's mother, Livia.
