The onetime holder of a Guinness world record honoring the lowest bass note ever reached, gospel pioneer J.D. Sumner was the driving force behind the Stamps Quartet, which earned secular renown as the longtime vocal support for Elvis Presley. Born November 19, 1924, Sumner became the Blackwood Brothers' bass vocalist in 1954, remaining with the group for a dozen years. At his suggestion, in 1955 the Blackwoods became the first touring act to travel from show to show in their own customized bus, a practice since followed by virtually every live performer.
