Dale Warren

Ken Curtis and Shug Fisher were replaced by Dale Warren (born Summerville, KY, June 1, 1925), a veteran of Foy Willing and the Riders of the Purple Sage, and Deuce Spriggens (born George R. Braunsdorf), a former member of Spade Cooley's band. The group's one-year stay at Coral proved no more successful than the last few years at RCA, however.

After Lloyd Perryman passed away, the leadership of the Sons of the Pioneers was taken over by Warren, who had joined in 1952. He carried the group into the 1990s. They continued to perform in concert and recorded as well with a lineup that featured Rusty Richards (vocals), Doye O'Dell (guitar, vocals), Billy Armstrong (fiddle), Billy Liebert (accordion), and Rome Johnson (vocals). These Pioneers, along with younger country music groups such as the Riders in the Sky, were a constant reminder of the legacy of this much-loved western group.

Robert "Sunny" Spencer was a self-taught musician who played 22 instruments. As a member of the Roy Rogers western music group, “The Sons of the Pioneers” for 22 years he performed nation wide and every summer at the Roy Rogers-Dale Evans Museum and Happy Trails Theater in Branson, Missouri. An all around entertainer with lots of humor, he sang lead vocals, played guitar, saxophone, banjo, trumpet, fiddle, clarinet and jug. His trademark song was "Mamma Don't Allow No Music Playin' Round Here," in which he performed on all of his instruments. He had a long varied musical career that included working with Al Hirt and Pete Fountain at the 500 Club in New Orleans, and with the Spike Jones band on, "The Midwestern Hayride" WLS radio show in Chicago in the early 1950s. He also led the Sunny Spencer Orchestra and the Sunny Spencer Trio, performing for many years at the Hacienda and Frontier Casinos in Las Vegas.
