James Lloyd Logsdon (April 1, 1922 – October 7, 2001) was an American country and rockabilly singer, songwriter and radio DJ. He performed country music as Jimmie (or Jimmy) Logsdon, and rockabilly music, including his best-known song "I Got a Rocket in My Pocket," as Jimmy Lloyd.
Logsdon was born in Panther, Kentucky, the son of a Methodist minister. He and his sister sang in choirs and took part in local talent contests, and he grew up listening to rhythm and blues as well as country music. He graduated from high school in Ludlow, Kentucky, in 1940, and married the same year, before starting work installing PA systems in nearby Cincinnati. He joined the Air Corps in 1944, and on leaving two years later opened a record and radio shop in La Grange, Kentucky. He learned the guitar, and began writing songs, performing regularly on radio station WLOU and in clubs as leader of a country trio. He made his first recordings for the local Harvest label in Cincinnati in 1951, and the following year joined station WKYW as senior announcer. He continued performing, and at a show in Louisville met his hero Hank Williams, who encouraged him to seek a recording deal.
