Joe Besser and Jimmy Little were signed on the strength of Besser's popular "army drill" routine, which they perform in the movie. It had earlier been "borrowed" for The Three Stooges' Boobs in Arms (1940).
If you see credits elsewhere for Frank and/or Harry Condos for this film, it likely came from bad information. Frank Condos and Nick Condos were the Condos Brothers in live performances from 1929 to the mid-30s, including 1 film in 1932. Harry was listed in a 1930 Playbill, but that's likely a misprint since Frank (also in the Playbill) was dancing with Nick at the time, and they took their act to Europe. All film credits after 1932 for Condos Brothers refer to brothers Nick and Steve Condos.
