Johnson's first single release was "Catfish Blues" / "So Sweet" (1962), plus he made numerous live appearances with Davis over that decade. In 1971 Johnson released Fast and Funky, but his live playing gradually reduced. A couple of low key albums appeared in the 1980s, before Johnson received more regular live work in the 1990s, particularly in Europe. Whilst there his output included Railroad Man (1990) and Blues for Harlem (1999). Two Gun Green followed in 2002.
