Hens are working in the “Flockheed Eggcraft Factory”, laying eggs for the war effort until they get distracted by a rooster singing like Frank Sinatra. Porky, the supervisor, rushes to investigate. Soon, he’s auditioning for a new crooner; among those showing up are caricatures of Al Jolson, ‘Jimmy Durante’ and Cab Calloway. He evetually gets to a Bing Crosby clone, who introduces himself as “The Old Groaner”. Between the two of them, egg production is soon more than he can handle.
