Glad you asked! Charles Fuller’s Old Fashioned Revival Hour became The Joyful Sound!
Wanting to keep the radio ministry alive after Dr. Fuller’s death on March 18, 1968, his son Dr. Daniel Payton Fuller and the Global Broadcasting Association continued the program.
David Allan Hubbard, the 3rd President of Fuller Seminary, became the program’s regular speaker from 1969 until 1981.
