Bonnie Baker born 1 April 1917

Bonnie Baker (April 1, 1917 – August 11, 1990) was an American singer of jazz and popular music and was known from 1936 to the end of her performing career as Wee Bonnie Baker. Her biggest hit was "Oh Johnny, Oh Johnny, Oh!," recorded with the Orrin Tucker Orchestra in 1939. 

Bonnie with Orrin Tucker

She was born Evelyn Underhill* in Orange, Texas. She attended school in Galveston and Houston. At age 16, during the 1932–1933 school year, she was a day student at Mount de Sales Academy, in Macon, Georgia, which at that time was a Roman Catholic boarding school for girls. She then moved back to Houston where she sang in night clubs. She joined Orrin Tucker's band as a vocalist in 1936, after Louis Armstrong suggested that Tucker recruit her. Tucker gave her the stage name "Wee" Bonnie Baker on account of her height, about 4-foot 11 inches. She had only local fame before joining Tucker's orchestra – wider notability did not occur until she performed at the Empire Room of the Palmer House in Chicago in 1939, when she began to flourish in the South and Pacific Coast. 

Baker’s career with Tucker was uneventful until the runaway success of “Oh Johnny, Oh Johnny, Oh!” a twenty-year-old World War I-era song which sold over a million-and-a-half copies. Baker’s singing style made her wildly popular in her own right, and she began to receive equal billing with Tucker. Her girlish voice was described as "like a tiny silver bell, soft but tonally true". In 1940, she was voted most popular female band vocalist in Billboard’s annual college poll. Throughout the 1940s, she remained the most highly-imitated singer in show business. She also had success with the songs "You'd Be Surprised", "Billy", "Would Ja Mind?", and "Especially for You". Baker made two Hollywood appearances while with Tucker’s orchestra, including the feature film You’re the One. She shared the cover of Down Beat magazine’s February 15, 1940, issue with pianist and bandleader Joe Sanders. 

She left the Tucker orchestra in February and out on her own in February, Baker’s popularity soared. When Tucker enlisted in the Navy in mid-1942, she turned down an offer to front the band in his absence. As a solo act traveling with her own vaudeville unit and singing with various orchestras, she was making far more money than she could on a band salary. She legally adopted her stage name, Bonnie Baker, on October 9, 1943, in Circuit Court, Chicago, Illinois.

She then continued with a solo career, singing with the USO (United Service Organizations) during World War II, and appearing regularly on the radio show Your Hit Parade. She also sang with other bands. Baker remained extremely popular through the mid-1940s. 

On January 30, 1943, she made the cover of Billboard and later that year sang several numbers in the Monogram feature film Spotlight Scandals. Baker’s popularity began to decline slightly after the war, though she continued touring and performing on the theater circuit as well as on radio and occasionally television. She recorded solo for the Memo label in 1946 and on Universal in 1948. In 1952, she recorded with Mel Blanc and Billy May on Capitol, singing opposite Blanc’s Porky Pig, Tweety and Sylvester characters and in 1956 she provided vocals for two Chilly Willy cartoons. That same year she released an album, Oh Johnny!, with orchestra conducted by Wilbur Hatch, on Warner Bros. Records.

Baker married four times during the 1930s and 1940s, the first to a man named Lakey in 1937. In October 1940, she and Tucker announced plans to wed. Even after she had left the band, in fall 1942, they apparently still intended to marry. How much of this was just the dreams of a publicity agent is unknown however. In interviews while with Tucker’s band, Baker typically insisted that she had no romantic interests in Tucker. In October 1943, she legally changed her name to her stage moniker and became engaged to a soldier, Lieutenant Johnnie Morse. The two married in December and were still together two years later. In March 1948, she married her manager, Frank Taylor. The couple had a child in October 1948 and divorced in October 1949. 

In spring 1950, Baker married comedy writer Bill Rogers. The pair teamed up, with Rogers playing guitar and writing specialty songs for her. Baker and Rogers continued performing as a team into the 1960s. Baker came to hate her signature song, as audiences always called for it. She grew tired of singing it, estimating that she performed it two thousand times each year. 

By 1975, Baker had married a fifth time, to a man named Gailey, a jazz guitarist and stage-act writer, also known as Billy Rogers. They moved to Fort Lauderdale in 1958 and performed in local clubs, such as Pier 66. She gave up singing in 1965, after a heart attack. By 1976, she was a switchboard operator at a Ft. Lauderdale medical center. She died in a Fort Lauderdale hospital in Florida on August 11, 1990 at the age of 73.
