Overton Amos Lemons, known as Smiley Lewis, was an American New Orleans rhythm and blues singer and guitarist. The music journalist Tony Russell wrote that "Lewis was the unluckiest man in New Orleans. He hit on a formula for slow-rocking, small-band numbers like 'The Bells Are Ringing' and 'I Hear You Knocking' only to have Fats Domino come up behind him with similar music with a more ingratiating delivery. Lewis was practically drowned in Domino's backwash."

New Orleans rhythm and blues is a style of rhythm and blues that originated in New Orleans. It was a direct precursor to rock and roll and strongly influenced ska. Instrumentation typically includes drums, bass, piano, horns, electric guitar, and vocals. The style is characterized by syncopated "second line" rhythms, a strong backbeat, and soulful vocals. Artists such as Roy Brown, Dave Bartholomew, and Fats Domino are representative of the New Orleans R&B sound.
