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.
The "road years" with the Larry Elgart band continued until 1960, when the road simply became too boring and too difficult for her. After two years on the road, she was still unknown, and there were no singing engagements to be had. She took various secretarial jobs booked through Manhattan temp agencies. She continued her working relationship with the former road manager of the Elgart band, who had become an agent in the office of the legendary Willard Alexander. This man, Bob Bonis, arranged for Carol to sing at a jazz festival in Pittsburgh in 1960, at which time she met Lambert, Hendricks and Ross.
Jon Hendricks asked Carol if she could learn the LH&R book in order to be prepared to take Annie Ross' place if that ever became necessary. Carol agreed to study the group's exacting material, and continued her secretarial gigs. Then, one night in early 1961, when attending a performance of LH&R at the Village Vanguard, Jon asked Carol to sing a couple of tunes on her own, after which the legendary proprietor Max Gordon asked her if she'd like to sing at the club the following August as opening act for Oscar Peterson. In her own words, "I stammered an acceptance, and walked five feet off the ground on the way home".
