Jimmy Dee is a rockabilly-rock and roll musician and singer from San Antonio, TX. He hit 47 on the Billboard Hot 50 in 1957 with the song "Henrietta", a rockabilly-style, early rock 'n' roll song that remained in the top 50 for ten weeks. He appeared on Dick Clark's American Bandstand TV program (Season 1, Episode 97) on December 4, 1957 during the 4:00 PM hour. Also featured were Danny and The Juniors. Jimmy Dee had by 1956 become a club attraction in lounges near San Antonio.

It is known that he was a member of the backing group for the Verve and MGM recording artist Sharon Wynter. He recorded and toured with her but did not sing on any of her recordings. He married her younger sister, Debra, in June 1967. The Sharon Wynter song Bad Dreams relates a bit of the story of the romance of Jimmy and Debra.

He worked as a session musician in Memphis and later in Nashville, Tennessee during the sixties. He is also credited on one of Del Shannon's tracks "Tell Her No", 1965, on drums and back-up vocals. It is thought he may have toured with Shannon as his drummer.

During the years 1967 and 1968, he worked sessions in Muscle Shoals, Alabama, both at FAME Studios and Muscle Shoals Sound Studios.
