After serving in the Air Force, Whitfield worked in the grocery business in Florida.
Several personnel changes followed including the additions Glen Allred in 1952 and Les Beasley in 1953.
He continued to manage and sing bass until he left the group in 1958 in order to avoid traveling away from his family.
Whitfield worked as a concert promoter across the South, helping to launch the Gospel Singing Jubilee television program.
Mr. Whitfield also sang bass in a little-known northwest Florida Southern Gospel Group called "The Workmen Quartet."
