Joe "Bebop" Carroll (November 25, 1919 – February 1, 1981) was an American jazz vocalist known for his work with Dizzy Gillespie between 1949 and 1953. Born Joseph Paul Taylor in Philadelphia, Pennsylvania, Carroll was a prominent figure in the jazz scene, particularly noted for his humorous collaborations with Gillespie on songs like "Swing Low, Sweet Cadillac" and "Oo Bla Dee." After joining Gillespie's big band in 1949, Carroll continued to perform with a smaller group formed by Gillespie after the big band dissolved a year later. In 1953, Carroll embarked on a solo career, recording several albums for Epic Records during the 1950s. His discography as a leader includes "Joe Carroll with the Ray Bryant Quintet" (1956), "School Days" with Dizzy Gillespie and Milt Jackson (1957), "Man with a Happy Sound" (1962), "The Bebop Singers" (1970), and "Jumpin' at Jazzmania" (1978). Carroll's work as a sideman with Gillespie is featured in recordings such as "Pleyel Concert 1953" and "Carnegie Hall Concert." His contributions to jazz, particularly in the bebop and scat singing styles, have left a lasting impact on the genre.
