The U.S. Army, one of the world's most prolific makers of motion pictures, excelled with this one, which may have been produced near where we are now sitting at the Astoria Studios. Homer, a soldier of rural or mountain origin, doesn't wash and is smelling up the barracks. His strangely benevolent buddies decide on a musical strategy to get him under the spray, and cook up new lyrics for folk songs. The remainder of the lengthy film is composed of musical sequences like "Fresh and Clean" and "Wash Your Socks." After films like this, it's no wonder that veterans-turned-students needed the remedial advice of films like Body Care and Grooming.
