Aside from his incredibly low bass voice, Sumner's business acumen helped promote Southern Gospel and move it into the mainstream of American culture and music during the 1950s and 1960s.
In 1949, Sunny South manager Horace Floyd relocated the quartet to Orlando, but Sumner stayed behind in Tampa where he maintained the sponsorship and started a new group, the Dixie Lily Harmoneers, which he sang with for a few months.
They split their time between Atlanta and Wheeling, West Virginia, with the occasional trip to Hollywood to sing in Western movies.
The lineup of Fred Daniel on tenor, Ed Wallace on lead, Ace Richman on baritone, and J. D. on bass continued on for five years until June 30, 1954.

Sumner was credited not only for his singing, songwriting, and concert promotions, but was also noted for being the first to customize a coach bus for the entertainment business to use for music groups.
"[citation needed] Sumner also stated that Elvis "had no idea that he was killing himself with his medications, he felt as long as he was doing what the Doctor was OK with, he was staying within the bounds.
