of converting an old RT bus into a mobile home. They enlist the help of their workmates in a musical segment that uses the track Seven Days to a Holiday. The scenes were shot at the works in 1962, during its annual summer shutdown. Filming included large parts of the works as well as numerous actual employees as extras. The rest of the film was shot in Greece. Soundtrack There are 16 song and musical numbers in the film: "Seven Days to a Holiday", "Let Us Take You for a Ride", "Stranger in Town", "Swinging Affair", "Really Waltzing", "Yugoslavian Wedding", "All At Once", "Summer Holiday", "Bachelor Boy", "Dancing Shoes", "Foot Tapper", "Big News", "The Next Time", "Les Girls", "Round and Round", and "Orlando's Mime".
