David Walker (May 5, 1941 – March 12, 1986), better known by his stage name Bunker Hill, was an American rhythm & blues and gospel singer. Born and raised in Washington, D.C., Walker sought a career in professional boxing, at one point becoming the sparring partner of Archie Moore. He left boxing to pursue a career singing gospel, and in the late 1950s joined the Mighty Clouds of Joy. In 1962 he was offered the chance to record a secular novelty song by manager Ray Vernon, the brother of Link Wray.
