The Ink Spots were a vocal group in the 1930s and 1940s that helped define the musical genre that led to rhythm and blues and rock and roll, and the subgenre doo-wop. They and the Mills Brothers, another black vocal group of the same period, gained much acceptance in both the white community and black community. Their songs usually began with a guitar riff, followed by the tenor Bill Kenny, who sang the whole song through.
