Seventy-two years ago this month, "the man with the action-packed expense account" made his two-fisted radio debut. Yours Truly, Johnny Dollar ran until 1962 and helped to bring down the curtain on the golden age of radio. We'll hear three radio adventures of "America's fabulous freelance insurance investigator," each starring a different actor as Dollar. First, Charles Russell stars in "Murder is a Merry-Go-Round" (originally aired on CBS on March 11, 1949). Then, John Lund is Dollar in "The Marigold Matter" (originally aired on CBS on January 23, 1953). Finally, Mandel Kramer plays Johnny in "The Three for One Matter" (originally aired on CBS on October 22, 1961).
