The fourth of seven children, John Royce Mathis was born on September 30, 1935 in Gilmer, TX to Clem and Mildred Mathis. As a small boy, the family moved to Post Street in San Francisco. It was there that he learned an appreciation of music from his father who taught him his first song, “My Blue Heaven”. At age eight, his father purchased an old upright piano for $25. When he brought it home, it wouldn’t fit through the front door.
