The FBI in Peace and War was an American radio crime drama inspired by Frederick Lewis Collins' book of the same name.
It aired on CBS from November 25, 1944, to September 28, 1958, produced and directed by Max Marcin and Betty Mandeville.
The show had a variety of sponsors over the years, including Lava Soap, Wildroot Cream-Oil, Lucky Strike, Nescafe and Wrigley's.
The theme was the March from Prokofiev's The Love for Three Oranges, arranged for small symphony orchestra by Amedeo De Filippi, with Vladimir Selinksy conducting.
The music was accompanied by a chant of "L-A-V-A," in reference to the show's sponsor being Lava soap.
