Johnnie Allan, real name John Allen Guillot, is a pioneer of the swamp pop musical genre.
Born March 10, 1938, in Rayne, Louisiana, Allan, a Cajun, grew up in a musical family, and at age six obtained his first guitar. By age thirteen he was playing with Walter Mouton and the Scott Playboys, a traditional Cajun music band. About two years later he switched to Lawrence Walker and the Wandering Aces, another traditional Cajun band.
In 1956 he saw Elvis Presley perform live on the Louisiana Hayride music program, and shortly afterwards Allan began to play rock and roll music. In 1958 he left Walker to form the Krazy Kats, and in doing so helped to pioneer what became known as swamp pop music.
That same year he recorded "Lonely Days, Lonely Nights" for the Jin label of Ville Platte, Louisiana, and the song became a swamp pop classic.
He later recorded for Mercury Records and the Viking label of Crowley, Louisiana, among others.
He returned to the Jin label in the early 1970s and went on to record many notable swamp pop tunes, including his versions of Chuck Berry's "Promised Land" and Merle Haggard's "Somewhere on Skid Row."
