When open auditions are announced for a radio variety program, the local station is besieged by aggressively over-coached "professional kids." Also auditioning is the International Silver String Submarine Band—which turns out to be the gang, equipped (or rather, armed) with home-made instruments.
They suffer through an endless parade of cute kiddie troupers, and accidentally knock over the microphone several times, which inadvertently blows tubes and bulbs in the control room, causing the hat worn by the sound man, played by vaudevillian Sid Walker, to be literally blown off his head, and making his hair stand on end. The gang then steal the show with a rendition of "The Daring Young Man on the Flying Trapeze."
Mike Fright was the first Our Gang short since Pups Is Pups to not contain the opening "Good Old Days" Our Gang theme song. Instead, it was replaced with the Leroy Shield incidental tune "Little Dancing Girl", which appeared as background music in many of the films and would be the music used for the first 4 minutes of this episode. Because the nature of this film was a talent show with a variety of musical selections, additional background music was not used, nor was it needed.
