Elvis Presley performed the song in the 1958 motion picture King Creole. The song uses the same "stop-time" riff as Muddy Waters' 1954 song "Hoochie Coochie Man" written by Willie Dixon. This particular riff is one of the most recognizable licks in blues and is also heard in Bo Diddley's "I'm A Man" (1955) and Muddy Waters' "Mannish Boy" (1955).

Indeed, the critical feature of the song is the use of stop time, or pauses in the music, during the first half of the progression. This musical device is commonly heard in New Orleans jazz, when the instrumentation briefly stops, allowing for a short instrumental solo before resuming. I hope you enjoy my take on it. Thanks for listening.
