BLUESOBIT: Arnold 'Gatemouth' Moore, the first blues singer to appear at Carnege Hall, has died at the age of 90. Born in Kansas in 1913, Moore moved to Kansas City at the age of 16 and started a career singing in dance bands. Moore survived the Natchez Rhythm Club Fire, an infamous event which claimed the lives of most of his colleagues in Walter Barnes' orchestra. Towards the end of the Second World War, Moore's first recordings for local labels brought him to the attention of natonal labels - including National Records, who brought him to New York and Chicago for the sessions where he was to record I Ain't Mad At You, Pretty Baby, Did You Ever Love A Woman? and Christmas Blues, Moore's first major successes. He moved to King Records, but during 1947 started a new career as a reverened. He didn't abandon music, however, working as a gospel artist and dj. In 1977, Johnny Otis persuaded Moore to make a brief return to the blues for a Blues Spectrum album.
