Mercy Dee Walton was born in Waco, Texas, United States, he moved to California just before World War II. He started playing piano at age 13 and learned his style from many of the ten-cent party house pianists that played out in the country on weekends. To make ends meet, he had to earn his living in the fields chopping cotton, picking grapes or cutting spinach. During this time, the musician who impressed Walton the most was Delois Maxey, who never had an opportunity to record. In 1949, Walton made his first record for the small record label, Spire Records in Fresno.
