An important figure in R&B music of the 1950s, he faded into obscurity in the 1960s and died while serving a prison sentence for manslaughter.

"Need Your Love So Bad", sometimes known as "I Need Your Love So Bad", is a song first recorded by Little Willie John in 1955. Called a "unique amalgam of gospel, blues and rhythm & blues", it was John's second single as well as his second record to reach the US charts.
