Carol Sloane was born to Claudia and Frank Morvan on March 5, 1937, in Providence, Rhode Island, the older of two daughters, but she never lived in that city. Instead, she spent her happy childhood in the small town of Smithfield, just a few short miles north of the city. Her parents worked steadily through the years of World War II in the textile mill near their home.
Carol was the lucky member of a large family of cousins, aunts and uncles who all possessed natural singing voices. Only one uncle ever received formal musical education, and he played the tenor sax. Carol and Ed DrewIn 1951, her Uncle Joe arranged an audition for her with a society dance band led by Ed Drew, and she began singing the stock arrangements of popular hits of the day each Wednesday and Saturday night at Rhodes-on-the-Pawtuxet Ballroom, located in Cranston, Rhode Island.
In 1955, Carol married a Providence disc jockey named Charlie Jefferds, and almost immediately, the couple found themselves at Fort Carson, Colorado where Charlie endured the rigors of basic training followed by a one-year obligatory tour of duty in Germany. They returned to the US in January 1958, and were amicably divorced in that year.
Carol continued to sing in small bars and clubs until she met the road manager of the Les and Larry Elgart Orchestra, which was touring the amusement park ballrooms in the southern New England area. She auditioned for Larry Elgart, who then asked her to come to New York with his band. The brothers had recently split the organization, Les taking the territory west of Chicago, Larry to handle everything east of Chicago. Larry Elgart suggested she change her name to Carol Sloane.
